A 44-year-old female patient presented with weight loss, diarrhea and intermittent episodes of left upper quadrant (LUQ) pain lasting for 3 years, accompanied by acute episodes of focal LUQ pain, dizziness, tachycardia, borborygmi and bloating, occurring approximately 60 min after meals. The patient developed chronic acalculous cholecystitis and transient exocrine pancreatic insufficiency after infection with Coxsackievirus B4 (CVB4), which resolved following laparoscopic cholecystectomy 2 years before the current presentation. Although imaging and functional investigation studies were unremarkable, a gastric transit study revealed rapid clearance of radiolabeled food, and the patient's symptomatology and gastrointestinal studies supported the diagnosis of late dumping syndrome. The patient's symptoms significantly improved with adherence to recommended dietary changes, including an increase in protein intake, abstinence from simple carbohydrates and avoidance of simultaneous consumption of beverages with food, following consultation with a dietitian.

We report the rare case of an acalculous, gangrenous cholecystitis on a, previously healthy, outpatient COVID-19 adult. The 53-year-old patient presented to the emergency department due to epigastric pain and fever and was admitted to the COVID-19 department. Due to clinical and laboratory deterioration, a computed tomography scan was performed that confirmed the diagnosis of acalculous cholecystitis. The patient was submitted to laparoscopic cholecystectomy. Intraoperatively, a gangrenous gallbladder was identified. Immunohistology validated the presence of specimen wall vasculitis and vessel thrombosis. [ABSTRACT FROM AUTHOR]

A 41-year-old female presented with an 8-month history of right upper quadrant pain, exacerbated by ingestion of saturated fats. The patient was positive for antibodies to Coxsackievirus serotype B4, established by an investigation incited by an acute episode of pleurodynia 8 months before the current presentation. Imaging studies including a hepatobiliary iminodiacetic acid scan showed no gallbladder structural or functional abnormalities. Laboratory studies indicated pancreatic enzyme insufficiency associated with below-normal lipase and amylase levels. Patient symptomology was consistent with cholecystitis with positive Murphy's sign, so cholecystectomy was recommended. Post-surgery pathological report confirmed chronic acalculous cholecystitis. Patient demonstrated full recovery, indicated by return of normal pancreatic enzymes levels and resolution of abdominal pain. [ABSTRACT FROM AUTHOR]

Haemorrhagic cholecystitis (HC) is a rare cause of cholecystitis that can be fatal if management is delayed. HC could present in the setting of trauma, malignancy and bleeding diathesis, such as renal failure, cirrhosis and anticoagulation. Its symptoms are easily confused with acute calculous or acalculous cholecystitis and might include haemobilia or hematemesis as blood drains from the gallbladder into the gastrointestinal tract. Imaging of HC can be misleading unless the possibility of this diagnosis is considered. In this report, we present an interesting case of HC in a patient with none of the above comorbidities and the patient who was not on anticoagulation neither anti platelets. The case includes relevant imaging and a review of the literature on this rare subject. [ABSTRACT FROM AUTHOR]

Acute acalculous cholecystitis remains an elusive clinical diagnosis possibly due to complex clinical setting in which this entity develops, lack of large prospective controlled trials that evaluate various diagnostic modalities, thus dependence on a small database for clinical decision making. Concealed gallbladder perforation is rare. Herein, we report an 82-year-old female who presented with a right upper quadrant pain and features of local peritonitis. Abdominal ultrasound was suggestive of cholecystitis while computed tomography (CT) scan reported a perforated gallbladder with pericholecystic fluid collection. The patient underwent successful cholecystectomy; and intra-operatively, similar findings as those reported on imaging were seen. Unfortunately, she succumbed shortly post-operatively due to pulmonary embolism. Our report highlights the importance CT scan in patients with vague abdominal symptoms followed by sudden resolution. It also reminds the importance of considering the diagnosis of concealed gallbladder perforation as a differential in patients with peritonitis, as it may be missed by routine radiological investigations.

Haemorrhagic cholecystitis is a seldom seen cause of right upper quadrant pain that can result in gallbladder rupture, massive intraperitoneal haemorrhage and death if untreated. Haemorrhagic cholecystitis is usually seen in the presence of cholelithiasis, malignancy, trauma and coagulopathies. Here, we present the unusual case of an elderly man presenting with acalculous haemorrhagic cholecystitis, who was successfully treated with laparoscopic cholecystectomy. We review the radiological and laparoscopic findings of haemorrhagic acalculous cholecystitis. This case highlights the importance of prudent use of radiological imaging to differentiate haemorrhagic cholecystitis from alternate pathology and early surgical intervention to avoid massive intraperitoneal haemorrhage and the high mortality with which it is associated.

Acalculous cholecystitis is a rare but life-threatening disease, but its pathogenesis is not fully revealed yet. We experienced two acalculous cholecystitis cases associated with aortic dissection. In Case 1, acalculous cholecystitis occurred just after the exacerbation of the aortic dissection. Laparotomy showed necrotized cholecystitis with fresh thrombi formation. Case 2 developed acalculous cholecystitis on the 65th hospital day of aortic dissection. Laparotomy revealed the perforation of the gallbladder. Histological study revealed fibrosis and hemosiderosis in the subserosal layer. The histological findings of these two patients are quite different: Case 1 is acute ischemic and Case 2 is chronic ischemic. While a few cases of acute ischemic cholecystitis have been reported previously, chronic acalculous cholecystitis (CAC) has not been documented. History of aortic dissection could be a risk factor of acute and CAC due to relatively decreased splanchnic blood flow. [ABSTRACT FROM AUTHOR]
