Hemangioma is one of the most frequently encountered benign hepatic neoplasm which can develop secondary degeneration. Sclerosed hemangioma is a rare disease histologically characterized by large amount of collagen and elastic fibril between sclerosed small vessels. Its differential diagnosis is very difficult. It should be included in the differential diagnosis of other hepatic lesions such as hepatocellular carcinoma, intrahepatic cholangiocarcinoma, and metastatic hepatic tumor. A 77-year old male was admitted with upper abdominal discomfort. Abdominal ultrasonography revealed GB stone, dilated common bile duct with bile duct stone, and a 4.6 cm sized hyperechoic mass at segment 5 and 6 of the liver. Abdominal dynamic computed tomography demonstrated dilated intrahepatic bile ducts and a 5X5 cm sized mass which showed minimally delayed enhancement. Abdominal magnetic resonance imaging revealed the mass with low signal intensity in T1 weighted image, high signal intensity and focal low signal in T2 weighted image which showed minimal enhancement. We removed common bile duct stone with endoscopic retrograde cholangiopancreatography then decided to undergo right lower segmentectomy of liver due to possibility of cholangiocarcinoma. Histopathological examination of hepatic mass showed large amount of fibrous tissue with occasional residual vascular channels. We describe one case of sclerosed hemangioma mimicking cholangiocarcinoma.
