Summary:A 58-year-old man undergoing treatment of hypertension and diabetes was referred our hospital with right hypocondralgia. Blood examination revealed white blood cell increase and slightly elevation of transaminase. Abdominal US and abdominal CT demonstrated small gallstones and intramural cystic lesions of the body of the gallbladder. MRI demonstrated the different content between the cystic lesions and the gallbladder. Laparoscopic cholecystectomy was performed, because the possibility of malignancy was negative. Histologically, the wall of cystic lesion was composed of fibrotic tissue with no lining epithelial cells. The Rokitansky-Aschoff sinus (RAS) lay scattered around the cystic lesions and the etiology was considered the cystic lesions due to blockade of RAS. Because intramural cystic lesion of the gallbladder is extremely rare, further experiments and accumulation of cases would be required.
