Development of bile duct cancer in a 26-year-old man after resection of infantile choledochal cystAnomalous arrangement of the pancreaticobiliary duct is considered to be a high-risk factor for biliary tract malignancy. We report a case of intrahepatic cholangiocarcinoma in a 26-year-old man after total resection of choledochal cyst with anomalous arrangement of the pancreaticobiliary duct at the age of 5 months. He had been doing well after total resection of the choledochal cyst; however, he suddenly presented with a spiky fever and abdominal pain in the right upper quadrant at the age of 26 years.
An 11-year-old male patient demonstrating cholangiocarcinoma associated with congenital biliary dilatationWe herein report an 11-year-old male patient demonstrating advanced cholangiocarcinoma associated with congenital biliary dilatation (CBD). This Japanese boy presented with abdominal pain lasting a few days, and a diagnosis of type IV-A CBD was made based on the findings of imaging studies using ultrasonography, computed tomography, and magnetic resonance imaging. These studies also revealed a wide flat lesion associated with a few small round masses in the dilated choledochus. Intraoperative cholangiography revealed the presence of pancreaticobiliary maljunction of CP type.
