A Rare Presentation of Xanthogranulomatous Cholecystitis as Bouveret's Syndrome.

The purpose of this paper is to present sonographic and CT imaging findings of xanthogranulomatous cholecystitis (XGC) presented as Bouveret's syndrome, a very rare cause of gastric obstruction. While the patient's physical examination, upper GI endoscopy, and radiological findings all pointed to Bouveret's syndrome, CT differential diagnosis suggested either XGC or gallbladder carcinoma, and the final diagnosis was done histopathologically. Our paper aims to increase awareness in radiologically diagnosing XGC cases by introducing the possibility of existence of Bouveret's syndrome.
