Choledochocele, corresponding to Todani type III choledochal cyst, is a rare congenital anomaly of the biliary tract characterized by cystic dilatation of the intraduodenal segment of the common bile duct at the level of the ampulla of Vater. It accounts for less than 5% of all choledochal cysts, and its diagnosis in adulthood remains uncommon. We report the case of a 63-year-old woman hospitalized for persistent cholestatic jaundice, revealing biliopancreatic duct dilatation without lithiasic or tumoral obstruction. The combined use of magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERCP) allowed the diagnosis of choledochocele to be established. This case highlights the importance of considering this rare entity in patients with unexplained persistent biliopancreatic duct dilatation, in order to avoid diagnostic and therapeutic delays.
