Abstract
A rare case of hepatic ciliated cyst was reported. A 44 years-old man visited to our hospital for work-up of cystic lesion adjacent to the gall bladder pointed out by ultrasonography as screening. Ultrasonography showed a solitary cyst (5×3cm) with a echogenic mass in it and CT showed a irregular low density area at the liver bed. ERC showed extrinsic pressure on the neck of the gall bladder. By ultrasonographically guided puncture of the cyst, viscous white mucous was obtained. Cystography showed a small filling defect in the oval cyst. Cystadenoma was suspected, so extended cholecystectomy was performed. The inner surface of the cyst was smooth and no tumor was found on it. Histologically, the cyst wall showed ciliated columner epithelium and smooth muscle bands, so the diagnosis of hepatic ciliated cyst was made.
