A young college-going male presented with worsening dyspnoea and palpitations for 6 months. He was diagnosed with rheumatic heart disease. The patient's echocardiogram showed not only rheumatic affection of the mitral valve with restricted leaflet movements, but there was also a calcified hyperechogenic mass attached to the atrial aspect of the anterior mitral leaflet, which signified a probable calcified thrombus or an organised vegetation; and a heterogenous, low-attenuating mass attached to the interatrial septum characterised as an atrial myxoma. Considering the gravity of the situation, the patient underwent a successful removal of intracardiac masses with a bioprosthetic mitral valve replacement urgently. Although reported, the occurrence of atrial myxoma with rheumatic heart disease is a rare phenomenon. Left atrial thrombus and myxoma can mimic each other and pose a diagnostic challenge even in today's era of multimodality imaging., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2025.

A woman in her early 60s presented with multiple transient neurological symptoms over the course of 20 months, including transient loss of power to her right lower limb. Initial workup with CT brain scan, carotid dopplers and ECG revealed no abnormality; however, MRI of the brain suggested recent ischaemic events in separate cortical territories. Subsequent transoesophageal echocardiogram revealed a large mobile mass histologically confirmed to be an atrial myxoma. This case highlights the challenges in diagnosing atrial myxomas and the importance of thorough workup including cardiac imaging for suspected cerebrovascular events. It also underscores the role of brain MRI when clinical suspicion for a cerebrovascular event persists despite a normal CT scan., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2025.

Introduction: Benign and malignant myxoid soft tissue tumors have shared clinical, imaging, and histologic features that can make diagnosis challenging. The purpose of this study is comparison of the diagnostic performance of a radiomic based machine learning (ML) model to musculoskeletal radiologists., Methods: Manual segmentation of 90 myxoid soft tissue tumors (45 myxomas and 45 myxofibrosarcomas) was performed on axial T1, and T2FS or STIR magnetic resonance imaging sequences. Eighty-seven radiomic features from each modality were extracted. Five ML models were trained to classify tumors as benign or malignant in 40 tumors and then tested with an additional 50 tumors using cross validation. The accuracy of the best ML model based on area under the receiver operating characteristic curve (AUC) was compared to the consensus diagnosis of three musculoskeletal radiologists. Correlation between radiologist confidence (equivocal, probably, consistent with) and accuracy was tested., Results: The best ML classifier was a logistic regression model (AUC 0.792). Using T1 + T2/STIR images, the ML model classified 78% (39/50) of tumors correctly at a similar rate compared to 74% (37/50) by radiologists. When radiologists disagreed, the consensus diagnosis classified 50% of tumors (7/14) correctly compared to 86% (12/14) by the ML model, though this did not reach statistical significance. Radiologists had a cumulative accuracy of 91% (30/33) when they rated their confidence 'consistent with' compared to 61% (31/51) when they rated their confidence 'equivocal/probably' (P = 0.006). For cases when radiologists rated their confidence 'equivocal/probably', the ML model had 76% accuracy (39/51)., Conclusions: A radiomic based ML model predicted benign or malignant diagnosis in myxoid soft tissue tumors similarly to the consensus diagnosis by three musculoskeletal radiologists. Radiologist confidence in the diagnosis strongly correlated with their diagnostic accuracy. Though radiomics and radiologists perform similarly overall, radiomics may provide novel diagnostic utility when radiologist confidence is low, or when radiologists disagree., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2025 Lawrenz et al.

Rationale: Thrombus is the most common occupying lesion in the cardiac chambers, it is often distinguished from cardiac neoplastic occupations. Among them, the most common is cardiac myxoma, whose imaging manifestations are often confused with thrombus. However, the 2 types of lesions have different therapeutic strategies and are both potentially high-risk sources of embolism, so early differentiation between intracardiac thrombus and cardiac tumor is essential. In this study, we intend to investigate the value of dual-energy computed tomography (CT) in the differential diagnosis of cardiac thrombus and myxoma by retrospectively analyzing the dual-energy CT-related parameters of 2 cases of intracardiac thrombus and 1 case of cardiac myxoma., Patient Concerns: Three cases of masses located in uncommon areas of the heart with comparable imaging characteristics are presented in this study., Diagnoses: Echocardiography revealed an isoechoic mass in the cardiac chambers, while CT scans showed a hypodense occupancy with varying morphologies. Postoperative pathology or follow-up after treatment confirmed 1 case as a right ventricular thrombus, another as a right atrial thrombus, and the third as a right ventricular myxoma., Interventions: In this study, we conducted a retrospective analysis of dual-energy CT-related parameters in 2 cases of intracardiac thrombus and 1 case of cardiac myxoma., Outcomes: Our findings indicate notable differences in the slopes of the energy spectral curves, mean iodine density, and effective atomic number between the intracardiac thrombus and myxoma cases., Lessons: Drawing upon existing literature, we propose combining different quantitative analysis methodologies to create a more objective foundation for distinguishing between cardiac thrombosis and myxoma., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2025 the Author(s).

Background: The differential diagnosis of cardiac myxomas (CM), the most common benign primary cardiac tumors, is broad and a thorough diagnostic workup is required to establish accurate diagnosis prior to surgical resection. Transthoracic echocardiography (TTE) is usually the first imaging modality used for diagnosis of suspected CM. In a single tertiary centre study, we sought to determine the accuracy, sensitivity, and specificity of TTE in the diagnosis of CM and to determine echocardiographic characteristics indicative of CM., Patients and Methods: We retrospectively analyzed clinical, echocardiographic, and pathohistological findings of 73 patients consecutively admitted for suspected CM., Results: After diagnostic workup, 53 (73%) patients were treated surgically at our institution. Based on preoperative TTE, patients were divided into a CM group (n=45, 85%) and non-myxoma (NM) group. Of the 53 pathohistological specimens obtained during surgery, 39 (73%) were CM. The sensitivity and specificity of preoperative echocardiography were 97% and 50%, respectively. The overall accuracy was 85%. All NM tumors were found in an atypical location and 72% of CM were found in a typical position in the left atrium (p < 0.001). Tumors in NM group were significantly smaller than CM (24.3 ± 13.2 mm vs . 37.9 ± 18.3 mm, p = 0.017)., Conclusions: Our study confirms very good accuracy of TTE in the diagnosis of CM. The most important echocardiographic characteristics to differentiate between CM and tumors of different etiology are tumor location and size. Smaller tumors presenting at an atypical location are less likely to be diagnosed as CM, and these require additional imaging modalities for accurate diagnosis., (© 2025 Polona Kacar et al., published by Sciendo.)

Aggressive angiomyxoma (AAM) is a rare kind of neoplasm derived from mesenchyma, which is easily confused with other superficial masses. Here, we present a 21-year-old young female with a 2-year history of a mass in the right vulva. The patient's laboratory analysis yielded unremarkable results. Ultrasound examination revealed the presence of a heterogeneous solid mass in the right vulva with blood flow. Enhanced computed tomography imagines showed a capsular neoplasm in the posterior the perineal region without obvious enhancement. The patient received surgery. Biopsy after surgery revealed that the tumor was AAM. The patient was followed up regularly. In this article, we will describe sonographic and computed tomography imagines, histologic features of AAM, and review the related literature., (© 2024 Wiley Periodicals LLC.)

Cardiac myxomas are the most common primary benign tumors of the heart. The occlusion of peripheral arteries and complete obstruction of the abdominal aorta by a tumor embolus presents with distinct clinical manifestations. Herein, we present the case of a 38-year-old male with acute paresthesia, muscle weakness, erythematous, and violaceous changes in skin color localized to the dorsum of the left forefoot initially treated as cutaneous vasculitis. Further studies revealed the total occlusion of the terminal abdominal aorta by a saddle embolus from a cardiac myxoma. A multidisciplinary team consisting of cardiothoracic and vascular surgeons were involved in treating the patient, which resulted in full resolution of the case. This paper details the progression of acute bilateral limb ischemia to chronic limb threatening ischemia resulting from the total occlusion of the terminal abdominal aorta by a saddle embolus., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Abstract: Cardiac myxomas extending from the right ventricle are uncommon and this rare condition is potentially associated with several risks and poor outcomes. We report the case of a patient with a right ventricular myxoma who had a recent haemorrhagic stroke due to an arteriovenous malformation. The preoperative and intraoperative managements were challenging and required several difficult choices by the medical team and consequently, a multidisciplinary approach and a benefit-risk evaluation were necessary to determinate timely surgical resection in an urgent situation, simultaneously avoiding delayed or improper treatments, achieving a successful outcome in a very high-risk situation., (Copyright © 2024 Annals of Cardiac Anaesthesia.)

Atrial myxoma, a rare benign tumour of the heart, predominantly affects women in the reproductive age group. There is no consensus on the monitoring and treatment of atrial myxoma in pregnancy, as the experience is limited to a few cases reported in the literature. We report a case of a pregnant individual referred with suspected left atrial thrombus, finally diagnosed to have pedunculated left atrial myxoma and underwent successful resection along with caesarean section, resulting in good maternal-fetal outcomes., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Purpose: This study aims to report clinicopathologic and imaging features of odontogenic myxomas (OM), highlighting uncommon findings., Methods: Clinicopathologic and imaging data of OMs diagnosed in the five Brazilian diagnostic pathology centers were collected and analyzed., Results: The series comprised 42 females (68.9%) and 19 males (31.1%), with a 2.2:1 female-to-male ratio and a mean age of 34.5±15.4 years (range: 4-80). Clinically, most OMs presented as painless intraoral swelling (n = 36; 70.6%) in the mandible (n=37; 59.7%). Multilocular lesions (n=30; 83.3%) were more common than unilocular lesions (n=6; 16.7%). There was no statistically significant difference between the average size of unilocular and multilocular OMs (p=0.2431). The borders of OMs were mainly well-defined (n=24; 66.7%) with different degrees of cortication. Only seven tumors caused tooth resorption (15.9%), while 24 (54.5%) caused tooth displacement. Cortical bone perforation was observed in 12 (38.7%) cases. Morphologically, OMs were characterized mainly by stellate or spindle-shaped cells in a myxoid background (n=53; 85.5%). Surgical resection was the most common treatment modality (n=15; 65.2%), followed by conservative surgery (n=8; 34.8%). Outcomes were available in 20 cases (32.3%). Seven of these patients had local recurrence (35%). Enucleation was the treatment with the highest recurrence rate (4/7; 57.1%)., Conclusions: OM has a predilection for the posterior region of the jaws of female adults. Despite their bland morphological appearance, they displayed diverse imaging features. Clinicians must include the OM in the differential diagnosis of osteolytic lesions of the jaws. A long follow-up is needed to monitor possible recurrences., (© 2024. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Rationale: Spermatic cord myxomas are rare benign tumors, typically characterized by the production of mucopolysaccharides. These tumors are infrequently found in the urinary system, making this case noteworthy., Patient Concerns: A 55-year-old male presented with a painless swelling on the right side of his scrotum, which had persisted for over 3 months. There were no associated symptoms, and the patient had no significant medical history., Diagnoses: Initial diagnostic workup included physical examination, ultrasonography, and CT scans, which revealed a 2 cm cystic nodule near the right spermatic vein. Postoperative histopathology confirmed the diagnosis of myxoma., Interventions: The patient underwent laparoscopic high ligation of the left spermatic vein and excision of the right spermatic sheath cyst. The surgery was successful, with the cyst being completely removed., Outcomes: Postoperative recovery was uneventful, and histopathological examination confirmed the benign nature of the tumor. Follow-up was advised to monitor for any recurrence., Lessons: Although rare, spermatic cord myxomas should be considered in the differential diagnosis of scrotal masses. Surgical excision is both diagnostic and therapeutic, providing a favorable prognosis with minimal risk of recurrence., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

We describe a comatose female patient after electroconvulsive therapy. Head imaging showed diffuse cerebral emboli. Transesophageal echocardiography showed left atrial myxoma which was resected soon thereafter. The article describes the presentation, complications and treatment of myxomas and discusses electroconvulsive therapy, its adverse events and the possible relation to myxoma embolization., Competing Interests: Declaration of competing interest We declare all authors had no conflict of interest.

Cardiac tumours are often an incidental finding; when they do cause symptoms, they can be systemic (pyrexia and fatigue), cardiac (arrhythmia, chest pain and obstructive) or embolic (stroke, pulmonary embolism (PE) and peripheral embolism). Different cardiac tumours have a higher prevalence in children when compared with adults, and each type of tumour has a predisposition for specific aspects of the heart. With current imaging modalities, it is possible to identify the location, haemodynamic impact and tissue characteristics of tumours, which can help diagnose the type of lesion and guide further management. This case is of an atypical appearance of a right ventricular mass, which was found incidentally following presentation with PE. The patient underwent successful surgical resection of the mass, which was identified as a myxoma. The patient is on imaging surveillance to monitor for recurrence. The case demonstrates the strengths and weaknesses of different imaging modalities, highlighting the importance of a multimodality approach to guide a diagnosis., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Cardiomyopathies cause most intracardiac thrombosis (ICT), and Behçet's syndrome (BS) is a rare inflammatory disease that can be responsible for a proportion of ICT. Other inflammatory disorders involved in the aetiology of ICT include antiphospholipid syndrome, Henoch-Schonlein purpura, COVID-19, and Loeffler endocarditis. ICT usually occur during the active phase of BS, and they have a close relationship with vascular involvement. Atrial myxomas are benign cardiac tumours arising from the interatrial septum. They can lead to a substantial acute phase response, making them difficult to distinguish from inflammatory diseases. In this case study, we present a 46-year-old female BS patient who presented with constitutional symptoms mimicking BS flare in a routine follow-up visit and was diagnosed with left atrial myxoma after administration of several lines of immunosuppressives. Then, she underwent surgical tumour excision, and a histopathological examination confirmed the diagnosis.In conclusion, atrial myxoma should be kept in mind first of all when suspecting ICT, and advanced imaging methods such as cardiac magnetic resonance imaging (MRI) should be used if necessary.

A 44-year-old woman presented to the emergency department status post incidental discovery of a large lingual mass identified during workup of a known intracranial neoplasm. The patient presented with a 4-month history of progressive altered mental status, somnolence, aphasia, and dysphagia; symptomology was attributed to the suprasellar tumor. Metastatic disease to the oral cavity was the primary differential diagnosis. Imaging demonstrated a 5.5 × 5.5 cm posterior tongue mass with near complete pharynx obstruction. Prompt debulking and pathology workup occurred. On postoperative day 1, the patient experienced complete resolution of all symptoms. Given rapid improvement, neurological decline was ultimately attributed not to the suprasellar mass but instead as being secondary to profound obstructive sleep apnea and ensuing sleep deprivation caused by the lingual tumor. This case describes the rare finding of a massive lingual superficial angiomyxoma with a synchronous cerebral neoplasm in which the latter functioned as a diagnostic distraction., (Copyright © 2024 American Association of Oral and Maxillofacial Surgeons.

A healthy 28-year-old woman, presenting with a chronic cough for approximately 6 months, was referred for echocardiography. The images revealed the presence of two masses in each atrium without an inter-atrial septal defect. No additional abnormalities were detected during the clinical examinations. Subsequently, the patient underwent a successful surgical procedure for the removal of the cardiac masses., (© 2024. The Author(s), under exclusive licence to Springer Nature B.V.)

We describe two cases of umbilical cord (UC) angiomyxoma diagnosed prenatally by sonography in the second trimester of pregnancy. In both cases, a complex mass was detected at the placental insertion site, characterized by an echoic nodule surrounding the umbilical vessels and distal edematous Wharton's jelly. Follow-up scans showed that the mass grew mainly at the expense of its edematous component, with normal uteroplacental Dopplers throughout the remaining of the pregnancy. However, late-onset fetal growth restriction complicated the progress of pregnancy, requiring delivery by Cesarean section at 37 weeks' gestation in both cases. Neonatal courses were unremarkable. An extensive review of the English literature was also performed, collecting 45 similar cases including ours. Our experience as well as the review of the literature confirms that UC angiomyxoma is an uncommon, sporadic condition that is usually detected incidentally during prenatal sonography and presents as an isolated finding. Nevertheless, it represents a high-risk condition for pregnancy complications including prematurity, fetal growth restriction, and fetal demise., (© 2024 American Institute of Ultrasound in Medicine.)

Background: Carney syndrome is an uncommon autosomal disorder closely linked to mutations in the PRKAR1A gene. Skin lesions are the most pronounced feature of Carney syndrome, affecting over 80% of individuals with this condition. This syndrome is characterized by a triad of myxomas, skin pigmentation, and endocrine hyperfunction, featuring multiple endocrine neoplasms with skin and cardiac involvement. Dilated cardiomyopathy, a primary cardiomyopathy, is defined as the dilation and impaired systolic function of the left or both ventricles. Its clinical presentation varies from being asymptomatic to heart failure or sudden cardiac death, making it a leading global cause of heart failure. Currently, Dilated cardiomyopathy has an estimated prevalence of 1/2500-1/250 individuals, predominantly affecting those aged 30-40 years, with a male-to-female ratio of 3:1. This case report describes a heart failure patient with cardiac myxoma caused by Carney syndrome combined with dilated cardiomyopathy. The patient was successfully treated for heart failure by heart transplantation., Case Presentation: Herein, we report a case of heart failure due to Carney syndrome that resulted in cardiac myxoma combined with dilated cardiomyopathy. A 35-year-old male was admitted to the hospital three years ago because of sudden chest tightness and shortness of breath. Echocardiography indicated myxoma, and a combination of genetic screening and physical examination confirmed Carney syndrome with cardiac myxoma. Following symptomatic management, he was discharged. Surgical interventions were not considered at the time. However, the patient's chest tightness and shortness of breath symptoms worsened, and he returned to the hospital. A New York Heart Association grade IV heart function was confirmed, and echocardiography indicated the presence of dilated cardiomyopathy accompanied by cardiac myxoma. Ultimately, the patient's heart failure was successfully treated with heart transplantation., Conclusions: Cardiac myxoma caused by Carney syndrome combined with heart failure caused by dilated cardiomyopathy can be resolved by heart transplantation., (© 2024.

Cardiac tumors are rare entities, among which atrial myxoma (AM) stands as the most frequent, accounting for approximately half of all reported cases. The incidence of AM is estimated to range from 0.001% to 0.3% within the general population, yet only about 0.06% of these cases present with coronary embolic events. We report on a 33-year-old male smoker who experienced acute, severe precordial pain radiating to the left upper limb, lasting for one hour. The electrocardiographic evaluation demonstrated ST-segment elevation in leads D2, D3, and aVF, alongside significantly elevated serum troponin levels, confirming a diagnosis of ST-segment elevation myocardial infarction (STEMI). Subsequent coronary angiography revealed proximal occlusion of the right coronary artery due to thrombus. An initial attempt of thrombus aspiration was unsuccessful, followed by primary angioplasty with balloon inflation without stent placement. Further diagnostic exploration through transthoracic echocardiography identified a homogenous, smooth-surfaced mass measuring 5.2 cm x 2.3 cm attached to the interatrial septum. This mass, characterized by lobulations, prolapsed into the mitral valve and left ventricle during diastole, consistent with AM. Surgical resection of the mass was successfully performed, with the patient being discharged asymptomatic. In the reported case, the patient's profile, notably his age, and gender, diverges from the typical epidemiological characteristics associated with AM. This case adds to the limited number of reports where the inferior wall is affected by the right coronary artery being occluded. This report emphasizes the significance of differential diagnoses in younger patients presenting with STEMI.

An 80-year-old female was referred to our institution due to transient right upper limb weakness. Transthoracic and transesophageal echocardiography revealed a tumor in the left atrium. The tumor was attached to the posterior wall of the left atrium near the atrioventricular node. Intraoperative pathological examination revealed that the tumor was a myxoma, and complete resection was successfully performed. However, she experienced persistent complete atrioventricular block postoperatively and required pacemaker implantation., (© 2024. The Author(s).)

A 51-year-old male with a complicated medical history presented with shortness of breath. Preoperative workup confirmed the presence of a large atrial mass. However, delayed gadolinium enhancement CMR with long inversion time (TI 600) showed lack of enhancement, which was suggestive of a thrombus. During cardiac magnetic resonance imaging, delayed gadolinium enhancement sequences with long inversion time (TI 600) are commonly used to distinguish between an avascular thrombus versus a vascular tumor., Competing Interests: The authors have no competing interests to declare., (Copyright: © 2024 The Author(s).)

Juxta-articular myxoma (JAM) is a rare soft tissue tumour predominantly composed of mucinous tissue and usually found around large joints. We report a 73-year-old woman with a 5-year history of a soft tissue mass in the thenar eminence of the right wrist who presented to our department. An initial diagnosis of a ganglion cyst was made using magnetic resonance imaging (MRI) and the jellied content of the mass by aspiration. Two years after presentation, surgical treatment with tumour resection and carpal tunnel release via the radial approach was performed because the symptoms of carpal tunnel syndrome worsened, and the tumour invaded the carpal tunnel. Histopathological examination revealed a JAM. At the 1-year follow-up, the symptoms of carpal tunnel syndrome had resolved, and no recurrence was confirmed by MRI. Level of Evidence: Level V (Therapeutic).

Background: Myxomas are the most common primary cardiac tumor and typically originate in the left atrium. Atrial myxomas may present following complications of obstruction and emboli. If an atrial myxoma goes untreated, complications such as congestive heart failure, embolic stroke, and sudden death can occur., Case Presentation: A 58-year-old Caucasian male presented following a cardiac arrest. He was taken emergently to the cardiac catheterization lab and received two drug eluting stents. Following the procedure, he was found to have a left atrial mass that was intermittently obstructing the mitral valve on echocardiography. After leaving the cardiac catheterization lab, he was hypotensive and placed on multiple intravenous medications for hemodynamic support as well as an Impella device. Following medical optimization, he underwent one vessel coronary artery bypass graft as well as surgical excision of the left atrial mass, which pathology had shown to be an atrial myxoma., Conclusion: This patient's case of cardiogenic shock following revascularization was complicated by the identification of an atrial myxoma, which, when large enough, can obstruct blood flow through the mitral valve leading to acute mitral dynamic stenosis. This condition results in circulatory collapse due to obstruction of the left ventricle in diastole as the myxoma occludes the mitral valve., (© 2024. The Author(s).)

Diagnosing atrial myxoma in pregnancy is challenging because patients may present with non-specific symptoms that might be overlooked. The timing of non-obstetric operation usually depends on the nature of the disease, after careful consideration of feto-maternal safety, including the use of cardiopulmonary bypass and placental transfer of anaesthetic drug. A woman in her 30s at 18 weeks of pregnancy presented with recurring dizziness. She underwent successful myxoma excision at 20 weeks under general anaesthesia and cardiopulmonary bypass. The 6×5 cm myxoma was histologically confirmed as myxoma. Early detection of atrial myxoma in pregnancy is crucial, and a clinician has to consider the diagnosis of left atrial myxoma with mitral valve obstruction as a cause of severe dizziness. Optimal outcomes require multidisciplinary management. In this case, surgery during the second trimester of pregnancy enabled a full-term pregnancy with the patient's and foetal well-being and normal postprocedural echocardiography., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Background: Stroke presentation secondary to a cardiac myxoma thromboembolism is rare in the pediatric population. Because of such rarity, the reported cases in the literature are primarily case reports. Additionally, general pediatric stroke management lacks evidence-based guidelines because of its low incidence and lack of clinical trials. In pediatric strokes identified from a cardiac myxoma, the incidence favors boys with the classical presentation of unilateral weakness and aphasia. We present a pediatric patient who presented with strokelike symptoms secondary to an intracranial embolus from a previously undiagnosed cardiac myxoma., Methods: We performed a systematic review by searching PubMed, Google Scholar, Web of Science, and Embase databases for cases of pediatric myxoma causing stroke (n = 2431) and identified 19 reported uses of surgical management in treating pediatric patients who present with stroke symptoms secondary to a cardiac myxoma thromboembolism., Results: The most common imaging modality was magnetic resonance imaging in 42% of cases, computed tomography in 36.8%, followed by computed tomography angiography in 31.6% of cases. Of these 19 children treated with procedures, 36.8% of pediatric patients aged between 4 and 14 years underwent neurosurgery (n = 7)., Conclusions: We describe an urgent mechanical thrombectomy and share preoperative and postoperative images and pathology slides confirming a stroke from myxoma origin. We provide added insight in the safe use of mechanical thrombectomy as treatment for pediatric strokes secondary to a thromboembolism., (Copyright © 2024 Elsevier Inc. All rights reserved.)

A previously healthy woman in late adolescence presented to the emergency department with stroke-like symptoms following a two-month history of bilateral foot pain and oedema, accompanied by a macular rash and progressive lower extremity weakness. On further investigation, she was found to have multiple cerebral emboli and a left atrial myxoma fixed to the interatrial septum. The patient subsequently underwent urgent surgical excision of the myxoma. On follow-up, her cutaneous and neurological symptoms were significantly improved. This case suggests that, in the presence of a vasculitic rash without evident or obvious cause, cardiac myxoma should be included in the differential diagnosis., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Background: Myxoma is a common type of primary cardiac tumor. However, there are few researches to illustrate challenge of safely inducing anesthesia in a patient with a giant right atrial myxoma at moderate altitude., Patient Concerns and Diagnoses: A 54-year-old female patient lived in a city with an average altitude of 1932 m with scheduled surgical treatment for giant right atrial myxoma, prompting discussions on appropriate anesthesia modalities given her prolonged residence at moderate altitude., Methods and Results: Considering the potential impact of moderate altitude on perioperative management, this study emphasizes the necessity of adequate volume preload therapy and the utility of transthoracic echocardiography or transesophageal echocardiography to prevent hemodynamic compromise. Furthermore, it highlights the unique consideration that, post-tumor removal, hypotension may not necessarily lead to decreased oxygen saturation in these patients., Conclusion: This case underscores the importance of avoiding hypotension, as pre-tumor resection blood pressure maintenance primarily determines blood oxygen concentration. Additionally, it sheds light on the intriguing observation that post-tumor removal hypotension may not result in decreased oxygen saturation. These findings have significant implications for the perioperative care of patients with giant right atrial myxoma at moderate altitudes., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Introduction: Primary cardiac myxomas are rare tumors. Concurrent valvular lesion is a common finding on evaluation which is thought to be due to annular dilatation secondary to tumor movement across the valve, functional obstruction across the valve, and severe pulmonary hypertension secondary to chronic obstruction. A common belief among surgeons is that excision of myxoma leads to abatement of symptoms, and further valve intervention may not be warranted., Methods: A 10-year retrospective descriptive study was designed to analyze patients who underwent excision of cardiac myxoma at our center. Data was analyzed regarding presenting features, echocardiographic findings of myxoma and valve morphology, intraoperative assessment, and postoperative outcome with/without valve repair/replacement in all patients., Results: A total of 22 patients underwent surgery for myxoma. Six patients underwent successful mitral valve repair with ring annuloplasty, two had moderate mitral regurgitation, three had severe mitral regurgitation, and one patient had no mitral regurgitation on preoperative assessment, but moderate mitral regurgitation was found intraoperatively. Four of these patients had no residual mitral regurgitation in follow-up period while two had mild residual mitral regurgitation. One patient had severe mitral stenosis of concurrent rheumatic etiology and successfully underwent mitral valve replacement., Conclusion: Cardiac myxomas are rare benign tumors commonly associated with mitral valve insufficiency. Mitral valve should be assessed intraoperatively after excision of mass as preoperative assessment might often be insufficient. Concomitant mitral valve intervention might be needed with a case-specific tailored approach, and mitral valve repair with ring annuloplasty offers best surgical outcome in such cases.

Cardiac myxoma is the most common primary benign cardiac tumors, mostly found in the left atrium. It was previously reported that the main component of myxoma was myxoid stroma riched in acid-mucopolysaccharide, the blood vessels in which were sparsely distributed, being characterized as hypovascular tumor by contrast echocardiography (CE) and computed tomography angiography (CTA). There are few reports of myxoma with rich blood supply and we report one in the left atrium., (© 2024 Wiley Periodicals LLC.)

Background: Echocardiography has been proven to be a useful tool for detecting atrial-occupying lesions, ranging from primary or secondary tumors to thrombi. Although the precise diagnosis is important as clinical treatment modalities differ, sometimes differentiating a thrombus from a myxoma is very difficult., Case Report: From January 2019 to December 2022, we retrospectively analyzed the echocardiographic findings of 8 patients who were found to have an interatrial mass. Of the 8 patients, 4 had a right atrial mass, and 4 had a left atrial mass. Based on ultrasonic examination, the initial diagnosis was a thrombus and the second diagnosis was a myxoma for all 8 patients. All masses were finally confirmed to be thrombi. Although an echocardiogram can provide significant information on the nature of atrial masses in many patients, qualitative diagnosis of a small percentage of atrial masses remains difficult., Conclusion: An atrial thrombus is occasionally difficult to differentiate from an atrial myxoma in patients without atrial fibrillation, especially when it is not attached to the left atrial appendage. Upon review of the echocardiographic findings of the 8 patients described in our study, it is essential to highlight the fact that a thrombus can mimic a myxoma and thereby create a diagnostic conundrum., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Aggressive angiomyxoma is a rare mesenchymal tumour, which usually appears in the pelvic region of women in their reproductive age. Although benign, it is a locally infiltrative tumour with frequent recurrence. We report a case of a pregnant woman in her 30s with a vulvar aggressive angiomyxoma which was initially misdiagnosed. Features of this case are discussed, highlighting the difficulty in its diagnosis and the challenge of the follow-up and treatment of recurrences., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2023.
