title: [A case of diverticular form type of congenital choledochal dilatation with anomalous arrangement of pancreaticobiliary duct].
abstract: We report a case of diverticular form type of congenital choledochal dilatation with anomalous arrangement of pancreaticobiliary duct and bile duct stone. The patient was a 63-year-old woman with the chief complaint of epigastralgia. Abdominal CT showed low density area suggesting cystic lesion at the region of pancreatic head. MRCP and ERCP revealed dilatation of the common bile duct in the multiple diverticular form with anomalous arrangement of pancreaticobiliary duct. A 2.0cm sized stone was also recognized in the dilated common bile duct. The patient underwent resection of gall bladder and dilated common bile duct, followed by hepatico-jejunostomy. Histological findings did not revealed malignant changes in the mucosa of both gall bladder and dilated common bile duct.
