Abstract

Hepatic duct diverticulum is a rare form of choledochal cyst that does not fit into the most widely used Todani classification system. Because of its rarity, it may be difficult for clinicians to diagnose and treat it. Here, we present a case of left hepatic diverticulum in a 57-year-old woman with epigastric pain. At presentation, there were mild elevations in the liver function tests. Computed tomography and magnetic resonance cholangiopancreatography showed diverticulum-like cystic lesion with sludge ball near the confluence portion of both intrahepatic bile duct, but the origin of the lesion could not be identified. The clinical impression was type II choledochal cyst. Surgical excision was planned due to recurrent abdominal pain. The operative findings revealed diverticulum arising from left hepatic duct. Histopathology confirmed the lesion to be diverticulum lined by biliary epithelium. The patient had no postoperative complication and no further symptoms since the operation.
