Kawasaki Disease With Acute Acalculous Cholecystitis: A Case Report

Acute acalculous cholecystitis (AAC) is an inflammatory disease of the gallbladder in the absence of gallstones. AAC has been linked to various systemic illnesses including Kawasaki disease (KD). We report a case of a five-year-old male brought to the emergency department (ED) with a history of fever and vomiting for four days. He was admitted as a case of KD. Then, we discovered that he had AAC, which was well managed by intravenous immunoglobulin (IVIG) as the fever subsided, C-reactive protein (CRP) decreased, and repeated abdominal ultrasound showed a decrease in gallbladder thickness without any evidence of coronary artery aneurysms.
