A left lateral bisegmentectomy was performed in a 29-year-old man presenting a primary lymphoma of the liver. Surgical exploration revealed a left-side gallbladder, located under the left lobe of the liver. During hepatic parenchyma dissection, performed strictly at the left of the round ligament and the umbilical portion of the left portal vein, common bile duct was injured. Complete separation of hepatic pedicle structures showed that the upper biliary convergence passed on the left side of the umbilical portion of the left portal vein before reaching the hepatoduodenal ligament. This case report discusses the embryological mechanism that could explain this uncommon bile duct abnormality, focusing on its consequences during left ruled lobectomy.
