Among the numerous anatomical variations in the hepatobiliary-vascular anatomy, Moynihan's hump, although rare, is a dangerous one. Failure of a surgeon to recognize it while operating can lead to complications like bile duct injury, bleeding and conversion to open surgery. We report a case of cholelithiasis, in which Moynihan's hump was identified during laparoscopic cholecystectomy and tackled with successfully. Further, we discuss the anatomy and surgical significance of this variation and conclude with the importance of adequate prior knowledge of hepato-biliary-vascular anatomy, achievement of critical view of safety and the use of indocyanine green dye as an adjunct to safely tackle this dangerous anomaly and prevent complications.
