Abstract
Xanthogranulomatous cholecystitis (CXG) is a rare entity of cholecystitis, characterized by the presence of xanthogranulomas within the gallbladder wall, that could be misdiagnosed as a vesicular carcinoma. We report a case of 66-year-old man with xanthogranulomatous cholecystitis associated with an incidental finding of a fusion of the planes of the liver which is a rare anatomic variant. Imaging especially ultrasounds, CT scan, and MRI play a key role in the characterization of those anomaly, thus avoiding a non-suitable surgical procedure.
