Duplication of the Gallbladder Associated with Choledocal Cyst: A Case Report

Introduction Gallbladder duplication is a rare anatomic malformation, which can now be detected by preoperative imaging study. Case presentation This is a retrospective case report of 39-year-old woman presented during a routine US (ultrasonography) examination complaining intermittent abdominal pain in the upper right quadrant. Laboratory examinations found normal values of total bilirubin, transaminases and alkaline phosphatase. US examination of the right upper quadrant was performed. It was noticed that the gallbladder was duplicated, but there were no distended wall thickening or presence of gallstone. A cystic lesion was noticed that was firstly identified as a pancreatic cyst. The MR cholangiography showed duplicated gallbladder with two cystic ducts and a choledochal cyst. ConclusionDuplication of the gallbladder is a rare congenital abnormality, which requires special attention to the biliary ductal and arterial anatomy. Laparoscopic cholecystectomy with intraoperative cholangiography seems to be the appropriate treatment.
