Imaging findings of gallbladder duplication due to two cases: case report and review of literature.

Duplication of the gallbladder, a rare congenital anomaly, is important in clinical practice as it may cause some clinical, surgical, and diagnostic problems. This anomaly is also important for surgeons due to the increased risk of complications especially after laparoscopic cholecystectomy. We report ultrasonography, computed tomography, and magnetic resonance cholangiopancreatography findings in two cases of a symptomatic duplicated gallbladder.
