Abstract:
A case of multiple hepatic cysts of the periductal gland located along the left intrahepatic bile duct is described. Ultrasonography and computed tomography disclosed many cystic lesions along the left portal vein in the left lateral segment of the liver. Percutaneous transhepatic cholangiography showed many compressed lesions. The resected specimen revealed multiple cysts of 2-7mm in diameter along the intrahepatic bile duct. Microscopically, cysts within the large Glisson's capsule were intermixed with lobuli of the periductal glands, thus suggesting periductal gland origin. Histopathological features of these cysts were similar to those of "multiple hilar cysts" reported by Nakanuma, but lack of portal hypertension and underlying chronic liver disease is the significant characteristics in this case which is different from "multiple hilar cysts".
