Gallbladder duplication with an incidence at autopsy of about 1 in 4000 is important in clinical practice, because it may cause some clinical, surgical, and diagnostic problems. Preoperative identification of this rare anomaly avoids biliary injuries and the other consequences of missed diagnosis. In this report, we present a case of ductular type duplex gallbladder diagnosed preoperatively by magnetic resonance cholangiopancreatography (MRCP) and ultrasound and managed successfully by laparoscopy.
