Fig. 1.

(A) Abdominal computed tomography scan shows large cystic lesions on arterial phase. (B) Magnetic reson-ance cholangiopancreatography scan also reveals large cystic lesions and adjacent small daughter cysts with high signal intensity on T2 weighted image without intramural nodules or septal wall thickening.

Fig. 2.

Endoscopic retrograde cholangiopancreatography shows a slight narrowing of common hepatic duct due to extrinsic compression and irregular stricture of intrahepatic duct without definite communication with cystic lesions.

Fig. 3.

Macroscopic and microscopic findings of biliary cystadenocarcinoma. (A) Macroscopically, mural nodules, papillary infolding and septal thickening are observed within the largest cyst. (B) Microscopic finding shows cystadenocarcinoma with columnar epithelium and abundant cytoplasm containing mucin (H&E, ×400).
