We report a case of Alonso-Lej II (diverticilum type) congenital choledochal cyst with bile duct stone. The patient was a 63-year-old man with the chief complaint of epigastralgia. A few hyperechoic masses in the gallbladder were detected by ultrasonography. Faint filling defects and extracanal pooling of contrast medium in the terminal common bile duct were revealed by ERG. Cholecystectomy, chloledocholithotomy and transduodenal papilloplasty were performed. A small diverticulum of the common bile duct and black stones in it and the gallbladder noted. Diverticulum of the common bile duct has been reported in 22 cases in the Japanese literatures. Adult cases numbered 13. These cases showed clinical aspects of bile duct stone, pancreatitis, and bile duct cancer, as well as Alonso-Lej I cyst
