Small veins entering the liver.
It is important to recognize and understand focal fatty infiltration and pseudolesions of the liver mimicking liver tumors on CT during arterial portography or helical-CT images. These conditions are caused by venous flow outside the main portal vein. Unless this is borne in mind, incorrect diagnosis and management may follow. This article demonstrates the appearance of the parenchymal changes caused by systemic venous flow and location of the systemic veins entering the liver parenchyma.
