Celiac trunk usually trifurcates and supplies the organs in the supracolic compartment. The vascular variations are common in this region. There are reports on the variant course of right hepatic artery (RHA). The tortuous RHA forming a caterpillar hump is a rare finding and also its providing origin to gastroduodenal artery (GDA) is an important observation. During routine dissection of abdomen of approximately 60-year-old male cadaver, concurrent arterial variations were observed. The celiac trunk bifurcated into splenic and common hepatic arteries. The left gastric artery arose from the abdominal aorta. The common hepatic artery was tortuous and divided into right and left hepatic arteries in front of portal vein. The RHA gave origin to GDA and then made a characteristic loop around the bile duct with the convexity to the right side. Knowledge of arterial variations of celiac trunk and its branches is useful in planning and executing the radiological interventions and surgeries in the supracolic abdominal compartment.
