A case of biliary cystadenoma

Abstract

A 36-year-old man with complaint of right back pain was admitted to our hospital. Ultrahowed multiple cystic lesions occupying 5x3 cm area in posterior segment of right lobe of the liver. Computed tomography (CT) scan revealed multilocular cystic lesion without calcification of the walls. Celiac angiography showed no tumor stain but dislocation of right hepatic artery. CT-angiography was useful to observed the vascular structure of the walls. Biliary cintigraphy demonstrated uptake of ^99mTc-N-pyridoxyl 5-methyl tryptophan (^99mTc-PMT) at a late phase. Under the diagnosis of biliary cystadenoma, sublobular resection was undergone. Histological examination showed high columnar epitherium producing mucin and confirmed the diagnosis of biliary cystadenoma. Diagnostic imaging modarities were done in a case of biliary cystadenoma and the characteristic findings were reported.
