Abstract

Patient: Male, 7-year-old Final Diagnosis: Acute liver failure with acalculous cholecystitis likely caused by an Influenza B infection Symptoms: Abdominal pain • fever Clinical Procedure: — Specialty: Pediatrics and Neonatology Objective: Unusual clinical course Background Acute acalculous cholecystitis (AAC) is a rare pediatric condition marked by gallbladder inflammation without gallstones. In children, symptoms are non-specific, making diagnosis and management challenging. Imaging, particularly ultrasound or computed tomography (CT) scan, often is the key to detection. Treatment typically involves supportive care and antibiotics, with surgery reserved for severe cases. This report describes the case of a 7-year-old Malaysian boy with a history of COVID-19 and influenza B infection presenting with acute acalculous cholecystitis. Case Report A 7-year-old Malaysian boy presented with fever, vomiting, and abdominal pain, initially diagnosed as acute gastroenteritis at primary care clinic.

Treatment with intravenous immunoglobulin (IVIG) therapy led to marked clinical and…

How strong is the evidence?

Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
