Xanthogranulomatous cholecystitis is rare, and information on its radiologic diagnosis is limited. Radiologic findings of two patients with histologically proven Xanthogranulomatouscholecystitis were reviewed. Sonography and computed tomography showed markedly thickened wall of gallbladder with stones, andpoorly defined border of the underlying liver. Radiologically, Xanthogranulomatous cholecystitis may be regraded as a tumor-like conditions, so ti should be included in the differential diagnosis of gallbladder cancer.
