Anatomic variations in the biliary tree may not be detected until adulthood and they can cause unexplained jaundice and biliary pain. Recognition of these anatomic variations is important to avoid an incorrect diagnosis and significant ductal injury during biliary surgery. Although there are numerous anatomic bile duct variations, an accessory cystic duct draining into the right hepatic duct is rare. We report a case of an accessory cystic duct draining into the right hepatic duct with cholelithiasis, in which the abnormality was identified by endoscopic retrograde cholangiopancreatography and magnetic resonance cholangiopancreatography and confirmed by laparoscopic cholecystectomy.
