title: Choledocholithiasis in anomalous biliary system.
abstract: Although congenital biliary abnormalities are common, preduodenal portal vein is very rare, not to mention preduodenal common bile duct (CBD) which has not been described before in the literature. A case with both anomalies complicated by biliary tract stones is reported. A brief review of embryonic development is also presented to explain the unusual biliary anatomy of this patient.
