Abstract
Variants of hepatic duct anomalies are widely discussed in the literature. Duplication producing a double and/or aberrant extrahepatic bile duct is one of the rarest congenital variants that have been sparingly reported. A 71-year-old female presented with right-sided abdominal pain. Computerized tomography demonstrated an enhancing soft tissue thickening in the gastric pylorus with extension into the left lobe of the liver and invasion of the left intrahepatic bile ducts and dilatation of the left intra- and extrahepatic biliary tract. Further examination led to a diagnosis of a double common bile duct with ectopic drainage into the gastric antrum. Recognition of this rare anomaly is of great importance because of the implications in respect of concomitant pathology, the potential short- and long-term sequelae and crucially for operative planning. Failing to appreciate the extent of anomalies may result in significant complications with the attendant morbidity.
