To document a rare anatomical variation featuring a bifurcated celiac trunk alongside a tortuous right hepatic artery forming a caterpillar hump.
Conducted a routine abdominal anatomical dissection of an approximately 60-year-old male cadaver (N=1).
Identified and traced branching patterns and anatomical pathways of the celiac trunk, hepatic arterial tree, and adjacent structures.
The celiac trunk presented as a hepatosplenic trunk bifurcating into splenic and common hepatic arteries, with the left gastric artery arising independently from the abdominal aorta.
The common hepatic artery coursed anterior to the portal vein before dividing into left and right hepatic arteries, with the right hepatic artery giving origin to the gastroduodenal artery.
The right hepatic artery followed a tortuous course forming a characteristic caterpillar hump loop with rightward convexity around the bile duct.
