Duplicate gallbladder: an unusual case report

Duplication of the gallbladder, a rare congenital anomaly, is important in clinical practice as it may cause some clinical, surgical and diagnostic problems. In this report we present a case of duplicated gallbladder diagnosed serendipitously in a 63-year-old male patient who had previously undergone successful laparoscopic cholecystectomy (confirmed histologically) approximately a year before for gallstones. The patient was re-admitted with obstructive jaundice. An abdominal computed tomography scan and magnetic resonance cholangiogram both revealed the presence of a gallbladder, which was thereafter removed at surgery undertaken to palliate the jaundice.
