Background: The co-occurrence of Lemierre's syndrome, primarily triggered by Fusobacterium necrophorum following oropharyngeal infection, with diabetic ketoacidosis (DKA) in diabetes mellitus (DM) patients, underscores a rare but life-threatening clinical scenario. Lemierre's syndrome induced DKA is extremely rare, with only one case report in adult and no case yet reported in elderly. Case Presentation: We reported a case of a 69-year-old female who presented with DKA triggered by deep neck space infection (DNSI), leading to rapid clinical deterioration within 6 h that necessitated high flow nasal cannula (HFNC) and antibiotic administration. Laboratory findings included leukocytosis, elevated serum C-reactive protein, hyperglycemia, ketonemia, and severe metabolic acidosis. Culture of the fluid from a neck mass puncture drainage and blood were positive for Klebsiella pneumoniae. The patient was further complicated by thrombosis of the left internal jugular vein with extension to the sigmoid and a neck abscess surrounding the carotid artery sheath, consistent with Lemierre's syndrome. This condition was managed aggressively with fluid resuscitation, insulin therapy, surgical drainage, antibiotics, and anticoagulation led to a significant improvement in her condition. Following a 13-day hospitalization, there was significant clinical improvement, culminating in the patient's discharge. Conclusions: The case highlights the need for greater awareness and understanding of the interrelated and mutually promoting conditions of DKA and Lemierre's syndrome among clinicians. Early recognition and treatment are crucial to prevent mortality in such complex cases. [ABSTRACT FROM AUTHOR]

Abstract Fusobacterium necrophorum is a Gram-negative anaerobic bacterium responsible for localized infections of the oropharynx that can evolve into bacteremia and/or septic thrombophlebitis of the jugular vein or peritonsillar vein, called Lemierre’s syndrome. To identify microbial genetic determinants associated with the severity of this life-threatening disease, 70 F. necrophorum strains were collected and grouped into two categories according to the clinical presentation: (i) localized infection, (ii) bacteremia with/without Lemierre’s syndrome. Comparative genomic analyses revealed two clades with distinct genetic content, one clade being significantly enriched with isolates from subjects with bacteremia. To identify genetic determinants contributing to F. necrophorum pathogenicity, genomic islands and virulence factor orthogroups (OVFs) were predicted. The presence/absence profiles of OVFs did not group isolates according to their clinical category, but rather according to their phylogeny. However, a variant of lktA, a key virulence factor, with a frameshift deletion that results in two open reading frames, was associated with bacteremia. Moreover, a genome-wide association study identified three orthogroups associated with bacteremic strains: (i) cas8a1, (ii) a sodium/solute symporter, and (iii) a POP1 domain-containing protein. Further studies must be performed to assess the functional impact of lktA mutation and of these orthogroups on the physiopathological mechanisms of F. necrophorum infections.

Abstract Purpose The purpose of this article is to report a case of Lemierre’s Syndrome producing unilateral endogenous endophthalmitis in a healthy, young woman with a history of tonsillitis. Case report/observations A 17-year-old healthy woman developed fever after a few days of sore throat. She later developed pneumonia with septic signs, leading to admission to the Intensive Care Unit. Lemierre Syndrome was diagnosed due to multiple septic pulmonary emboli and signs of sepsis following a recent episode of tonsillitis. During hospitalization, the patient complained of decreased visual acuity and floaters in her left eye. Ophthalmological examination revealed papillary edema, vitritis, foci of chorioretinitis in the macula and Roth’s spots, confirming the diagnosis of endogenous endophthalmitis. Subsequently, she underwent appropriate treatment, progressing satisfactorily. Conclusion and importance Although ophthalmological manifestations are rare, due to the pathophysiological characteristics of Lemierre’s Syndrome, all patients should underwent standard ophthalmologic assessment, even in the absence of ophthalmic symptoms or visible findings, as part of a multidisciplinary management approach.

Introduction: Lemierre’s syndrome is septic thrombophlebitis of the internal jugular vein, most commonly associated with head and neck infections. While central catheters are associated with venous thromboembolism and catheter-associated bacterial infections, cases of Lemierre’s syndrome caused by central catheters are extraordinarily rare.Case Report: We detail a case of Lemierre’s syndrome resulting from a peripherally inserted central catheter in a pregnant female patient. Diagnosis of this rare and potentially life-threatening disease process was expedited using point-of-care ultrasound.  Conclusion: Diagnosis of rare but potentially life- or limb-threatening pathologies is paramount to the successful practice of emergency medicine. Identifying these rare disease processes requires a high index of suspicion and a work-up strategy that includes consideration of medical history in combination with lab and imaging findings to determine appropriate interventions.

We report a case of a syndrome first described by French bacteriologist André Lemierre nearly 100 years ago. A young woman presented with fever, chest pain and arthralgia. Admission investigations revealed thrombocytopenia, cavitating pneumonia and an internal jugular vein thrombus. Blood cultures were positive for Fusobacterium necrophorum and Streptococcus constellatus. Respiratory failure developed within 48 h and was managed with high-flow nasal oxygen in a critical care setting. The investigation findings leading to diagnosis, as well as the antimicrobial and anticoagulation management strategies, are discussed. Lemierre's syndrome is rarely encountered by non-specialists, but a good outcome can be expected with prompt diagnosis and treatment.

Lemierre’s syndrome is a rare disease characterized by thrombophlebitis of the internal jugular vein and metastasis to distant organs. It occurs after an anaerobic infection of the larynx or dental region; the central nervous system involvement is infrequent. A 50-year-old woman presented with impaired consciousness. She had undergone several days of dental treatment for a toothache before presentation. Contrast-enhanced computed tomography (CT) revealed a head-and-neck abscess and a massive thrombus in the internal jugular vein, and a diagnosis of Lemierre’s syndrome was made. After symptoms improved with surgical drainage and antimicrobial therapy, the patient was discharged on day 58. In this case, Lemierre’s syndrome was complicated by a venous stroke caused by venous congestion due to a massive cerebral venous thrombus. Venous stroke due to thrombi may occur in patients with Lemierre’s syndrome, and magnetic resonance imaging or CT with venous phase imaging may aid in the diagnosis.

Abstract Background Lemierre’s syndrome is a fatal and rare disease that is typically characterized by oropharyngeal infection and internal jugular vein thrombosis. Timely institution of appropriate antibiotics is the standard treatment. Case presentation The authors report a case of Lemierre’s syndrome. A 67-year-old male patient of Han ethnicity in China suffered from a large inflammatory neck mass involving left internal jugular vein thrombosis diagnosed as Lemierre’s syndrome and finally cured by surgical treatment. In addition, a literature review was carried out through PubMed using the terms “Lemierre’s syndrome/disease and review, meta-analysis or retrospective study” and “Lemierre’s syndrome/disease and internal jugular vein”. This search yielded six articles that recorded surgical methods such as drainage, craniotomy, tooth extraction, and ligation of the occluded vein to give clinicians more ideas about the treatment of the Lemierre’s syndrome. Conclusion This is the first review to summarize the conditions under which surgical treatment are conducted. Additionally, this is the first report of such a large inflammatory neck mass that was completely cured by surgical resection and internal jugular vein ligation. The authors also offer several conclusions regarding surgical intervention in Lemierre’s syndrome for the first time.

Background: Lemierre syndrome is a rare, potentially fatal complication of oropharyngeal infections characterized by septic thrombophlebitis of the internal jugular vein. It primarily affects healthy adolescents and young adults. Its incidence declined after the antibiotic era, but it may have resurged in recent decades, likely due to judicious antibiotic use and increasing bacterial resistance. Prompt diagnosis and treatment are imperative to prevent significant morbidity and mortality. Methods: Lemierre syndrome has been called “the forgotten disease,” with a reported incidence of around 3.6 cases per million. The mean age at presentation is around 20 years old, though it can occur at any age. Lemierre Syndrome follows an oropharyngeal infection, most commonly pharyngitis, leading to septic thrombophlebitis of the internal jugular vein. F. necrophorum is the classic pathogen, though other organisms are being increasingly isolated. Metastatic infections, especially pulmonary, are common complications. Contrast-enhanced CT of the neck confirming internal jugular vein thrombosis is the gold standard for diagnosis. Long-course broad-spectrum IV antibiotics covering anaerobes are the mainstays of the disease’s treatment. Anticoagulation may also be considered. Mortality rates are high without treatment, but most patients recover fully with appropriate therapy. Conclusions: Lemierre syndrome should be suspected in patients with prolonged pharyngitis followed by unilateral neck swelling and fevers. Early diagnosis and prompt antibiotic therapy are key, given the potential for disastrous outcomes if untreated. An increased awareness of Lemierre syndrome facilitates its timely management.

Key Clinical Message The use of anticoagulants in Lemierre's syndrome is not well‐defined, lacking clear evidence for their efficacy. This report describes a patient with complete occlusion of the internal jugular vein by a thrombus who did not develop expected complications due to the formation of collateral venous channels.

BackgroundLemierre’s syndrome is a rare and serious complication of pharyngitis with an estimated annual incidence of 1 in 100,000 people worldwide. It is characterized by septic thrombophlebitis of the internal jugular vein with metastatic infection, usually after oropharyngeal infection. Rare cases of Lemierre’s syndrome have been reported to be caused by odontogenic infection.Case reportA 33-year-old male visited our hospital with symptoms of fever and sore throat for 16 days. The other symptoms included pain in his left neck and shoulder. In addition, metabolic syndrome was diagnosed based on waist circumference, diabetes, and hyperlipidemia. Fusobacterium necrophorum bacteria was detected using the metagenomic next-generation sequencing (mNGS) technique. The enhanced computerized tomography (CT) scan showed thrombosis of the left proximal jugular vein and brachiocephalic vein. Based on these observations, Lemierre’s syndrome was diagnosed. The etiology was that the fillings in the root canal tooth were lost with no blood or pain about 2 weeks before the onset. The patient recovered after treatment with antibiotics and blood purification.ConclusionLemierre’s syndrome should be evaluated for patients with fever, sore throat, and neck pain. If the loss of fillings from root canal therapy occurs, especially for those with metabolic syndrome, we should be aware of the possibility of this disease. Furthermore, the mNGS test can be used as a crucial supplementary diagnostic tool for patients with undetermined fever.

Introduction: Head and neck photoimmunotherapy (HN-PIT) uses a combination of drugs and laser illumination to specifically destroy tumor cells. Lemierre’s syndrome is an infectious disease with severe systemic symptoms caused by prior infection in the pharyngeal region, leading to thrombophlebitis. Here, we report a case of Lemierre’s syndrome that developed after HN-PIT for recurrent nasopharyngeal carcinoma. Case Presentation: A 68-year-old male with nasopharyngeal carcinoma (squamous cell carcinoma) underwent HN-PIT after local recurrence with chemoradiation therapy. Three months after HN-PIT, the patient developed fever and neck pain, which led to a diagnosis of Lemierre’s syndrome. The patient was treated with antibiotics and anticoagulants for at least 1 month. The patient’s general condition and inflammatory findings on blood sampling showed gradual improvement, and a follow-up cervicothoracic computed tomography imaging showed that the venous thrombus had been obscured and the patient was doing well. Conclusion: HN-PIT is a high-risk procedure for the development of Lemierre’s syndrome due to irradiation-induced mucositis, and anticipating the development of Lemierre’s syndrome during HN-PIT is important.

This article discusses a case of Lemierre's syndrome, a rare and severe condition characterized by bacterial oropharyngeal infection with septic thrombophlebitis of the jugular vein. The patient in this case study presented with symptoms of fever, sore throat, and sputum production, and was later diagnosed with Lemierre's syndrome along with a rare complication of cervical epidural abscess. The article provides details of the patient's treatment, including antibiotic therapy, and highlights the importance of prompt and adequate management for this condition. The article also mentions the potential association of Epstein-Barr virus infection with the pathogenesis of Lemierre's syndrome. [Extracted from the article]

Infection is a rare cause of panhypopituitarism and has not been reported in the context of Lemierre's syndrome. We present the case of a previously well 19-year-old man, who presented acutely unwell with meningitis and sepsis. Fusobacterium necrophorum was isolated from peripheral blood cultures and identified on cerebrospinal fluid with 16S rDNA Polymerase Chain Reaction (PCR). Imaging demonstrated internal jugular vein thrombosis with subsequent cavernous venous sinus thrombosis. Pituitary function tests were suggestive of panhypopituitarism. The patient was diagnosed with Lemierre's syndrome complicated by meningitis, cavernous sinus thrombosis, base of skull osteomyelitis, ischaemic stroke and panhypopituitarism. He was treated with 13 weeks of intravenous antibiotics followed by 3 weeks of oral amoxicillin, and anticoagulated with dalteparin then apixaban. His panhypopituitarism was managed with hydrocortisone, levothyroxine and desmopressin. [ABSTRACT FROM AUTHOR]

Lemierre’s syndrome is a rare clinical syndrome of septic thrombophlebitis following a bacterial oropharyngeal infection. Lemierre’s syndrome can be difficult to recognise and has significant morbidity. We report the case of a young man with Lemierre’s syndrome caused by Streptococcus pyogenes, who responded well to 2 weeks of beta-lactam therapy. Contributions: This case report summarises the key presenting features of Lemierre’s syndrome and provides a brief literature review considering the South African context.

Abstract Background Given the widespread prevalence of the coronavirus disease 2019 (COVID-19), oral and neck examinations tend to be avoided in patients with suspected or confirmed COVID-19. This might delay the diagnosis of conditions such as Lemierre’s syndrome, which involves symptoms resembling COVID-19-related throat manifestations. Case presentation A 24-year-old man without any underlying conditions was diagnosed with COVID-19 7 days before presentation. He was admitted to another hospital 1 day before presentation with severe COVID-19 and suspected bacterial pneumonia; accordingly, he was started on treatment with remdesivir and meropenem. Owing to bacteremic complications, the patient was transferred to our hospital for intensive care. On the sixth day, the patient experienced hemoptysis; further, a computed tomography (CT) scan revealed new pulmonary artery pseudoaneurysms. Successful embolization was performed to achieve hemostasis. In blood cultures conducted at the previous hospital, Fusobacterium nucleatum was isolated, suggesting a cervical origin of the infection. A neck CT scan confirmed a peritonsillar abscess and left internal jugular vein thrombus; accordingly, he was diagnosed with Lemierre’s syndrome. The treatment was switched to ampicillin/sulbactam, based on the drug susceptibility results. After 6 weeks of treatment, the patient completely recovered without complications. Conclusion This case highlights the significance of thorough oral and neck examinations in patients with suspected or diagnosed COVID-19 for the detection of throat and neck symptoms caused by other conditions.

Abstract Background Lemierre’s Syndrome is a severe medical condition that can result from oropharyngeal infection, typically caused by Fusobacterium necrophorum, leading to sepsis, internal jugular vein thrombosis, and metastatic septic emboli. However, there is limited literature on this syndrome caused by Streptococcus anginosus, and few previous cases have been reported to have deep neck space infection. We present the first case of Lemierre’s Syndrome caused by Streptococcus anginosus with deep neck abscess. Case presentation A 53-year-old male patient with no significant medical history presented with right neck pain after accidentally swallowing a fish bone one month ago. Laryngoscopy did not reveal any abnormalities. Five days prior to admission, the patient developed high fever. Imaging studies showed internal jugular vein thrombosis and a neck abscess surrounding the carotid artery sheath. Blood culture results were positive for Streptococcus anginosus infection, and the patient was diagnosed with Lemierre’s syndrome. The patient underwent surgical drainage and received antibiotics and anticoagulant therapy, and had satisfactory clinical progress. He was discharged after a 16-day hospitalization. Conclusions Although Lemierre’s syndrome is rare, it needs attention because it can lead to serious complications and requires timely treatment. Deep neck space infections can be life-threatening and doctors must be aware of its potential severity.

Pulmonary infection caused by Fusobacterium necrophorum, an obligate anaerobic gram-negative bacterium, most commonly occurs as a part of Lemierre’s syndrome, i.e., pharyngotonsillitis complicated by septic thrombophlebitis of the internal jugular vein and secondary lung abscesses. A 51-year-old previously healthy man was admitted to our hospital with pleuritic right-sided chest pain. No sore throat, dysphagia, or neck pain was observed. Chest radiography and computed tomography (CT) revealed massive right pleural effusion and bilateral bronchopneumonia. Right thoracic drainage yielded purulent fluids, from which a pure culture of F. necrophorum was isolated. Blood culture and broad-range polymerase chain reaction for bacterial 16S ribosomal ribonucleic acid on blood samples were negative. CT scan showed no evidence of internal jugular vein thrombosis or peritonsillar abscess. The right thoracic tube was removed after the purulent fluids were no longer drained. Although the antibiotic treatment was continued with intravenous sulbactam/ampicillin, to which F. necrophorum was sensitive, left purulent pleural effusion emerged. The antibiotic was switched to clindamycin, cefazolin, cefotiam, and flomoxef. Although the left pleural effusion gradually decreased, the right purulent pleural fluid was reaccumulated. Thus, the patient underwent right-sided thoracoscopic decortication and debridement, followed by thoracic lavage through a chest tube with saline solution. After the surgery, the patient’s condition improved, and no recurrence of pleural effusion was observed. This report presents the case of a previously healthy patient with bilateral parapneumonic empyema caused by F. necrophorum, without manifestations of pharyngotonsillitis, bacteremia, or Lemierre’s syndrome. Extensive thoracic drainage, effective antibiotics, and timely surgical interventions are imperative.

Lemierre’s syndrome, or postanginal sepsis, is an uncommon but potentially fatal infection of the internal jugular vein. The combination of bacteremia, internal jugular vein thrombophlebitis, and metastatic septic emboli secondary to acute pharyngeal infections is characteristic of Lemierre’s syndrome. Isolated pathogens are typically oral anaerobic bacteria, most commonly Fusobacterium necrophorum. While the incidence of Lemierre’s syndrome has declined over the years, the proportion of cases caused by uncommonly implicated bacteria have been increasingly cited in the literature (1). In this case report, we introduce a novel presentation of Lemierre’s syndrome in a patient who presented to the emergency department with neck swelling and shortness of breath and was found to have infectious myositis and bacteremia with methicillin-resistant Staphylococcus aureus. Clinicians should be vigilant of underlying thrombus in patients with neck swelling and infectious myositis as our patient’s internal jugular vein thrombus was missed on initial computed tomography read.

Key Clinical Message: Isolated mesenteric vein thrombosis associated with Fusobacterium is rare. Physicians should be aware regarding the association of Fusobacterium with thrombosis at various sites. [ABSTRACT FROM AUTHOR]

Lemierre's syndrome is a triad consisting of oropharyngeal infection, internal jugular vein thrombophlebitis, and systemic embolisation typically involving lung and brain. Orbital involvement in this life-threatening condition is rare but potentially blinding and may be an indicator of intracranial involvement. We describe a case of odontogenic Lemierre's syndrome complicated by extensive orbital and intracranial septic venous thrombosis, with optic and cranial neuropathy resulting in monocular blindness and ophthalmoplegia. A multidisciplinary approach with abscess drainage, antibiotic and antithrombotic therapy, and close radiological monitoring was critical for preserving contralateral vision and neurological function. [ABSTRACT FROM AUTHOR]

Lemierre's syndrome is a rare condition characterized by Fusobacterium bacteremia from an oropharyngeal source with septic emboli causing internal jugular vein (IVJ) thrombophlebitis in an otherwise young and healthy host. Rare variants of this rare disease have been described impacting the gastrointestinal, pulmonary, neurologic, musculoskeletal, soft tissue, and genitourinary systems. We discuss a case of an abdominal variant of Lemierre's syndrome. An otherwise young and healthy male presented with two pyogenic hepatic abscesses, Fusobacterium necrophorum bacteremia, and local hepatic venous thrombosis. The hepatic abscesses were percutaneously drained, he received broad-spectrum antibiotics and therapeutic-level anticoagulation, and he showed marked clinical improvement over a six-day hospital course. He was discharged with four weeks of daily oral and intravenous (IV) antibiotics, six months of direct oral anticoagulation, and close follow up. Clinicians should consider thrombophlebitis in more anatomical locations than the IVJ which is found classically in Lemierre’s syndrome in the setting of Fusobacterium bacteremia.

Background Lemierre's syndrome is an infectious phenomenon characterized by oropharyngeal infection with bacteraemia, thrombophlebitis, and distant septic emboli. Septic emboli are a recognized cause of a Type 2 myocardial infarction, with a left ventricular pseudoaneurysm being a rare but important complication of this. Case summary A 19-year-old male presented with acute confusion, fevers, and a cough. Blood cultures were positive for Fusobacterium necrophorum and initial imaging showed a cavitating pneumonia. Further evaluation revealed septic emboli in the distal digits and brain. The patient initially responded to antibiotic therapy but developed chest pain with increased troponin levels. An electrocardiogram showed inferolateral ST elevation. A transthoracic echocardiogram (TTE) showed hypokinaesia of the mid to apical lateral wall, and a computed tomography (CT) scan showed a pericardial effusion with a possible purulent effusion or abscess. The patient underwent surgical drainage of a sterile effusion. A post-operative TTE and CT demonstrated a left ventricular pseudoaneurysm that was surgically repaired. The venous thrombus was encountered intra-operatively confirming a diagnosis of Lemierre's syndrome. The patient completed the regimen of antibiotics and showed a good post-operative recovery. Discussion This is the first case described of left ventricular pseudoaneurysm as a complication of Lemierre's syndrome. It highlights not only the importance of serial, multimodality imaging in both diagnostic workup and identification of complications, but also the importance of a multidisciplinary team in the management of patients with complex and rare presentations.

Key Clinical Message Isolated mesenteric vein thrombosis associated with Fusobacterium is rare. Physicians should be aware regarding the association of Fusobacterium with thrombosis at various sites.

Key Clinical Message: The use of anticoagulants in Lemierre's syndrome is not well‐defined, lacking clear evidence for their efficacy. This report describes a patient with complete occlusion of the internal jugular vein by a thrombus who did not develop expected complications due to the formation of collateral venous channels. [ABSTRACT FROM AUTHOR]

Background: Familiarity breeds complacency. One case of sore throat can start to sound like another. However, even common viral and bacterial infections can lead to serious sequelae. Clinicians cannot make a diagnosis if they do not consider it in their differential. Case: The presentation – and subsequent hospitalization – of a septic 19 year-old male college student is described. Despite brief interval improvement, he became hypoxic one week after developing a sore throat and was ultimately diagnosed with Lemierre's syndrome (septic thrombophlebitis of the internal jugular vein) via blood cultures and advanced imaging. Conclusions: Though rare, Lemierre's syndrome carries a high mortality rate. It should be considered an emergent complication of head and neck infections, particularly in young adults.

Objective: to describe a case of severe sepsis and complicated bacteremia caused by Arcanobacterium haemolyticum and review similar cases in the literature. Case summary: A 26-year-old gentleman with a history of epilepsy presented with symptoms of sore throat, productive cough, periumbilical abdominal pain, watery diarrhea, nausea and vomiting, subjective fevers along with progressive jaundice for seven days. The patient had acute fulminant liver failure, septic shock, and Multi-organ failure. He required vasopressors, underwent intubation, and had grown Arcanobacterium haemolyticum in the blood and Bronchoalveolar lavage samples. He developed a peritonsillar abscess and cavitary pneumonia and required chest tube drainage followed by thoracotomy for hemothorax. The patient improved on Ampicillin-Sulbactam treatment and was treated with a total antibiotic duration of 6 weeks. He fully improved on post-discharge follow-up. Discussion: Arcanobacterium haemolyticum is a Gram-positive (sometimes Gram variable), catalase-negative facultatively anaerobic, non-motile, non-spore-forming, and variably β-hemolytic and is known to be a cause of pharyngitis and skin and soft tissue infections. Rarely A. Haemolyticum can be associated with severe systemic infections such as infective endocarditis, systemic abscesses, osteomyelitis, and septicemia. In previous literature reviews, the source of A. haemolyticum depended on the host, and pharyngeal and upper respiratory sources were likely to be associated with immunocompetent hosts. Conclusion: A. haemolyticum should be included in the differential diagnosis of bacterial pharyngitis complicated by severe systemic illness. Penicillins are the most commonly used antibiotics for treating A. haemolyticum bacteremia, and macrolides can be used for Penicillin’s treatment failure.

Introduction: Lemierre's syndrome is a serious condition that carries with it a high rate of morbidity and even mortality.Objective: This review highlights the pearls and pitfalls of Lemierre's syndrome, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence.Discussion: Lemierre's syndrome is a condition marked by septic thrombophlebitis of the internal jugular vein (IJV), with the classic triad of pharyngotonsillitis, IJV thrombosis, and septic emboli resulting in metastatic abscess. It typically begins as pharyngitis, often caused by Fusobacterium necrophorum. Patients most commonly present with fever, recently diagnosed pharyngitis, and neck pain or swelling. Septic emboli may affect multiple organ systems, most commonly the pulmonary system. The disease should be considered in patients with prolonged symptoms of pharyngitis, pharyngitis that improves but then worsens, critically ill patients with pharyngitis, patients with pharyngitis and infection at a secondary site, and neck signs/symptoms. Diagnosis includes throat and blood cultures, as well as imaging to include computed tomography of the neck and chest with intravenous contrast. Additional imaging of other areas should be performed as clinically indicated. Initial management includes hemodynamic stabilization with intravenous fluids and vasopressors as needed, as well as broad-spectrum antibiotics. Anticoagulation for the primary thrombus and possible septic emboli is controversial and should be considered in a multidisciplinary approach with admission.Conclusions: An understanding of Lemierre's syndrome can assist emergency clinicians in diagnosing and managing this potentially deadly disease.

We report a case of a syndrome first described by French bacteriologist André Lemierre nearly 100 years ago. A young woman presented with fever, chest pain and arthralgia. Admission investigations revealed thrombocytopenia, cavitating pneumonia and an internal jugular vein thrombus. Blood cultures were positive for Fusobacterium necrophorum and Streptococcus constellatus. Respiratory failure developed within 48 h and was managed with high-flow nasal oxygen in a critical care setting. The investigation findings leading to diagnosis, as well as the antimicrobial and anticoagulation management strategies, are discussed. Lemierre's syndrome is rarely encountered by non-specialists, but a good outcome can be expected with prompt diagnosis and treatment., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Crown Copyright © 2024.

Pulmonary infection caused by Fusobacterium necrophorum , an obligate anaerobic gram-negative bacterium, most commonly occurs as a part of Lemierre's syndrome, i.e., pharyngotonsillitis complicated by septic thrombophlebitis of the internal jugular vein and secondary lung abscesses. A 51-year-old previously healthy man was admitted to our hospital with pleuritic right-sided chest pain. No sore throat, dysphagia, or neck pain was observed. Chest radiography and computed tomography (CT) revealed massive right pleural effusion and bilateral bronchopneumonia. Right thoracic drainage yielded purulent fluids, from which a pure culture of F. necrophorum was isolated. Blood culture and broad-range polymerase chain reaction for bacterial 16S ribosomal ribonucleic acid on blood samples were negative. CT scan showed no evidence of internal jugular vein thrombosis or peritonsillar abscess. The right thoracic tube was removed after the purulent fluids were no longer drained. Although the antibiotic treatment was continued with intravenous sulbactam/ampicillin, to which F. necrophorum was sensitive, left purulent pleural effusion emerged. The antibiotic was switched to clindamycin, cefazolin, cefotiam, and flomoxef. Although the left pleural effusion gradually decreased, the right purulent pleural fluid was reaccumulated. Thus, the patient underwent right-sided thoracoscopic decortication and debridement, followed by thoracic lavage through a chest tube with saline solution. After the surgery, the patient's condition improved, and no recurrence of pleural effusion was observed. This report presents the case of a previously healthy patient with bilateral parapneumonic empyema caused by F. necrophorum , without manifestations of pharyngotonsillitis, bacteremia, or Lemierre's syndrome. Extensive thoracic drainage, effective antibiotics, and timely surgical interventions are imperative., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper, The authors declare nothing to disclose.None., (© 2024 The Authors.)

Lemierre syndrome describes septic thrombophlebitis of the internal jugular vein (IJV) and metastatic spread of the infection following a recent oropharyngeal infection in a setting of bacteremia caused by Fusobacterium necrophorum. Lemierre-like syndrome describes similar clinical scenario with no preceding oropharyngeal infection and/or in the setting of non-Fusobacterium cause. We report a case of Lemierre-like syndrome in a setting of Enterobacter cloaca bacteremia without known preceding oropharyngeal infection. History and physical exam revealed an irritable infant with cough, tachypnea, low grade fever, bilateral lung crepitations and features of infantile seborrheic dermatitis on the scalp. Imaging revealed thrombosis of right internal jugular vein and superior vena cava, bilateral pulmonary cavitary lesions and collections consistent with septic pulmonary emboli. Multiple rim enhancing hypo-dense liver lesions and chest wall collections consistent with abscesses were also seen. He was managed with parental antibiotics, drainage of the chest wall abscesses and discharged with clinical and radiologic improvement., (© 2024 The Authors.

This case report presents a rare instance of facial vein thrombophlebitis, a potentially serious complication, following a facial skin infection. A 33-year-old man known to have cerebral palsy, epilepsy on ventriculoparietal shunt, and kyphoscoliosis presented to the emergency department complaining of small facial wound and swelling for 1 week. The wound failed topical management and fever started to develop. His medications included quetiapine and levetiracetam. Investigations, including computed tomography, were carried out to rule out an extension to deep tissue. Management in the emergency department involved initial resuscitation with 500 mL of 0.9% normal saline and 1 L of lactated ringers, antibiotic coverage with piperacillin/tazobactam and vancomycin was given, and analgesia for pain control. This case highlights the potential for facial vein thrombophlebitis as a complication of facial skin infections. Early diagnosis and prompt initiation of appropriate management are crucial to prevent potentially fatal consequences., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)

Lemierre's syndrome is a rare disease characterized by septic thrombophlebitis of the internal jugular vein with septic emboli causing multifocal infection. This syndrome is most commonly seen after an upper respiratory tract infection in the adolescent population. We present a case of a teenage patient diagnosed with Epstein-Barr Virus (EBV) who presented to our tertiary care facility in multisystem organ failure with initial findings concerning for necrotizing fasciitis of the retroperitoneum. The patient underwent surgical debridement with frank purulence in the retroperitoneal space and emphysematous osteomyelitis of the right ilium. F. necrophorum was isolated from surgical specimens which led to the suspicion of Lemierre's syndrome. Further work up revealed internal jugular vein thrombosis, as well as multifocal inoculation with infection in the ankle, hip, chest, and neck confirming the clinical diagnosis. Lemierre's syndrome is associated with significant morbidity and can be fatal if not promptly recognized and treated. Therefore, early identification is essential to providing appropriate medical and surgical care.

We report a case of a 17-year-old female who presented with orbital cellulitis and meningeal involvement secondary to severe paranasal sinusitis with positive blood culture for Fusobacterium necrophorum. The patient recovered after a 2-month course of systemic antibiotics and functional endoscopic sinus surgery.Fusobacterium necrophorum-induced orbital cellulitis is a rare entity, with only 5 previous cases reported in the literature, which are reviewed here as well. This review reveals that Fusobacterium necrophorum is an aggressive pathogen in orbital cellulitis and therefore we suggest that affected patients may require a correspondingly aggressive medical management. Furthermore, we advise additional workup to rule out Lemierre's syndrome, a severe complication of Fusobacterium necrophorum infection, including transthoracic echocardiogram, chest radiograph, upper extremities' venous duplex and magnetic resonance venography.

Introduction: We describe here a case of a woman admitted to our Internal Medicine Unit for multifocal pneumonia. During the stay, she presented a few neurological symptoms: headache, nausea, emesis, photophobia, and gait disturbance. Methodology: Chest computed tomography (CT) detected multiple areas interpreted as septic emboli. Moreover, a left internal jugular thrombosis (LIJT) was incidentally reported. A CT-angiography showed the LIJT extension to cerebral sinuses. Ear, nose, and throat consultation revealed a left medium otitis. Anticoagulation with Fondaparinux was associated to antibiotic therapy with improvement in neurological symptoms that totally remitted over the next 2 weeks. Results: These findings confirmed the diagnosis of a Lemierre's Syndrome with thrombosis extension to cerebral sinuses. The genetic thrombophilic panel showed a heterozygosis for prothrombin gene G20210A mutation and the patient was discharged with Rivaroxaban for home continuation of anticoagulant therapy for at least 6 months. Conclusion: The prevalence of inherited thrombophilias in Lemierre's Syndrome is unknown and to our knowledge, this article is the first to identify a prothrombin gene G20210A mutation in a patient with Lemierre's Syndrome with thrombosis extension into the cerebral venous system. Exploring patients with Lemierre's Syndrome for underlying thrombophilia could clarify whether this promotes retrograde jugular vein thrombosis extension. [ABSTRACT FROM AUTHOR]
