Duplication of gallbladder with a common neck: A rare anatomical malformation.

Summary: Gallbladder duplication is a rare congenital anomaly. We report a rare case of double gallbladder in a young female, which was missed on ultrasonography, but was successfully treated by open cholecystectomy. It is paramount for an operating surgeon to be familiar with the anatomical details of the biliary system to prevent any inadvertent injury to the common bile duct and hepatic artery.
