Abstract

A choledochal cyst is a rare congenital anomaly of the biliary system manifested as the cystic dilatation of bile ducts, usually occurring in the common bile duct. Here, we describe an unusual type of choledochal cyst in a 45-year-old male that did not fit into the most widely accepted Todani classification of these cysts. The lesion mimicked duplication anomalies of the gallbladder and was finally diagnosed as a choledochal cyst involving the confluent portion of both intrahepatic ducts.
