抄録

A 60-year-old man who had been followed up for cholesterosis of the gallbladder, was admitted to our hospital because of right upper abdominal distention and pain. Ultrasonography depicted an enlarged gallbladder with multiple tiny hyperechoic polypoid lesions. No gallstones were found. These findings were considered to represent a diffuse type of cholesterosis associated with acute cholecystitis. This patient underwent laparoscopic cholecystectomy after conservative treatment had improved acute cholecystitis. Pathologic examination of the surgical specimen demonstrated that cholesterosis involved the cystic duct as well as the entire gallbladder. The wall of the gallbladder neck and the cystic duct was thickened with inflammatory cell infiltration, which was compatible with cholecystitis. Cholesterosis in the gallbladder neck and the cystic duct seemed to obstruct bile outflow. The present case indicates that cholesterosis can cause acute cholecystitis.
