title: Choledochal cysts and multilocular cysts of the pancreas.
abstract: Choledochal cyst is a rare congenital anomaly of the biliary system that may be associated with other abnormalities of the hepatobiliary tract. We report a case of an 11-year-old boy in whom the preoperative evaluation revealed a choledochal cyst and intraoperative cholangiopancreatography showed a cystic mass in the pancreas. Examination of the choledocho-pancreatico-duodenectomy specimen showed a multilocular cyst in the pancreas in addition to a segmental dilation of the common bile duct. The findings in our case adds pancreatic cyst to the spectrum of abnormalities associated with choledochal cyst and may also support the theory that choledochal cyst is the predominant abnormality in a widespread spectrum of the pancreatobiliary duct dysplasia.
