We report a rare case localized without cholangitis, which was difficult to differentiate from cancer preoperatively. Patient: A 56-year-old man suspected disease or admitted our ward. The serum IgG4 level elevated at 721 mg/dL. Computed tomography (CT) demonstrated focal wall fundus. Drip infusion cholecystocholangiography CT revealed no dilation, stenosis, border irregularity bile duct. Results: For diagnostic treatment purposes, cholecystectomy wedge resection bed performed. pathological diagnosis cholecystitis. Conclusion: It in cases involving In similar cases, surgical mind might be performed based on present clinical knowledge.
