On the inferior and posterior surfaces of the right hepatic lobe you can identify three distinct impressions: the fossa for the gallbladder on the inferior surface, the groove for the IVC on the posterior surface, and the porta hepatis on the inferior surface where the hepatic vessels and ducts enter the liver. The gallbladder lies in its dedicated fossa on the underside of the right lobe, the IVC runs along a groove on the posterior aspect, and the porta hepatis sits at the liver’s hilum on the inferior aspect. These three landmarks together define the surfaces in question. Impressions like the stomach or duodenal fossae aren’t the characteristic markings of the right lobe’s inferior/posterior surfaces, and the portal vein is a structure that forms part of the porta hepatis rather than a separate surface fossa.
