Clinical Practice and Cases in Emergency Medicine

Acute acalculous cholecystitis (AAC) is a rare, potentially serious disease that has been associated with Kawasaki disease (KD) in children. Studies suggest that patients presenting with severe abdominal symptoms secondary to KD have increased resistance to intravenous immunoglobulin (IVIG), and a higher rate of coronary artery aneurysms. We describe an eight-year-old boy who presented to the emergency department with severe abdominal pain and was diagnosed with AAC and KD. He was treated with IVIG and high-dose aspirin, achieving good response with complete symptom resolution. He had no coronary artery aneurysms or further complications and was discharged after three days.
