Abstract:
Choledochocele is a congenital abnormality of the biliary system, which characterized by a cystic dilatation of intramural segment of the distal common bile duct. Choledochocele manifests as cystic lesions in the duodenal lumen and resembles duodenal duplication cysts in imaging. We reported a patient with choledochocele. Magnetic resonance cholangiopancreatography showed a thin-walled sac in the duodenal cavity and a fine tubular structure connecting with the end of the common bile duct. Magnetic resonance cholangiopancreatography is a noninvasive and convenient technique in the diagnosis of choledochocele.
