An aberrant right hepatic artery was visualized between the portal vein and inferior vena cava in 20 of 100 patients examined by computed tomography. The origin of this aberrant vessel from the celiac or superior mesenteric artery was visualized in five cases. It is important to recognize this as a normal variant, especially if surgery in the area of the hepatoduodenal ligament is planned, so as to avoid necrosis of the right lobe of the liver.
