MR cholangiopancreatography of a case with a biliary tract variation and postoperative biliary duct injury

Because of the increasing frequency of surgical procedures such as hepatic resection, partial liver transplantation, and laparoscopic cholecystectomy, the number of patients requiring biliary imaging has increased. In this report, magnetic resonance cholangiopancreatography findings of a case with an aberrant right posterior hepatic duct draining directly into the gallbladder, which was overlooked prior to laparoscopic cholecystectomy, is presented and the importance of magnetic resonance cholangiopancreatography in the evaluation of congenital biliary anomalies and iatrogenic bile duct injury is discussed.
