title: Gallbladder agenesis.
abstract: This case report describes unusual congenital biliary anatomy encountered at a routine laparoscopic cholecystectomy. Imaging obtained prior to surgery (ultrasonography and magnetic resonance cholangiopancreatography) had been misleading. The case highlights the importance of careful dissection even with anticipated normal anatomy.
