Cystic artery pseudoaneurysm

Abstract

Cystic artery pseudoaneurysm (CAP) is a rare entity, with just a few cases reported in the literature. The most common presentation of CAP is described by Quincke's triad of upper gastrointestinal bleeding, jaundice and right upper quadrant abdominal pain. We report the case of an 83-year-old male who presented to the adult emergency with a history of an acute cholecystitis 5 weeks prior for which responded to conservative management. Despite this patient not presenting with Quincke's triad, early suspicion of CAP was considered in light of his history of acute cholecystitis and a computed tomographic CT abdomen ordered promptly which showed a 6 mm cystic artery pseudoaneurysm and a thick-walled gallbladder with surrounding inflammatory changes. Management with an endovascular approach followed by an elective cholecystectomy was done.
