The Usefulness of Magnetic Resonance Cholangiopancreatography in the Diagnosis of Infantile Congenital Choledochal Cyst : Report of a Case

We report herein the case of a 5-year-old girl found to have a congentital choledochal cyst. The patient was admitted to hospital for investigation of epigastralgia and vomiting and a choledochal cyst was subsequently diagnosed by ultrasonography (US) and abdominal computed tomogrophy (CT). A magnetic resonance cholangiopancreatography (MRCP) revealed a congenital choledochal cyst with anomalous pancreatico-biliary ductal union. Thus, resection of the diated bile duct with a cholecys tectomy and hepaticoduodenostomy were performed. Her postoperative course was unremarkable and she was discharged on postperrative day 40. MRCP is a new noninvasive imaging techmique used for visualizing the biliary ducts, the advantages of which include its safety, high sensitivity, and assurasy. It is also more costeffective than most other examinations, with the exception of ultrasonography and CT without use of sontrast material.
