Abstract

Xanthogranulomatous cholecystitis is a rare form of chronic gallbladder inflammation that is characterized by a severe proliferative fibrosis and has rarely been described in the radiologic literature. Like xanthogranulomatous pyelonephritis, it is an entirely benign but unusual expression of a reactive process and may be confused with a malignant neoplasm. Histologically, foamy histiocytes, multinucleated giant cells, other inflammatory cells, fibrous reaction with spindle cells, cholesterol cleft and noncaseating granuloma were found. Treatment of this benign inflammatory condition requires cholecystectomy to remove the focus of inflammation, control subsequent infection and relieve symptoms A case of xanthogranulomatous cholecystitis mimiking carcinoma of the gallbladder on abdominal USG, abdominal CT, and ERCP examination is presented with brief review of the literature.
