Parenchymal changes caused by liver hemodynamic alterations (pseudotumor).

Small areas of liver tissue are known to be supplied by a "third inflow" venous system separate from the usual dual blood supply of the portal vein and hepatic artery. This is a normal variant and it is composed of aberrant veins or parts of normal veins that directly enter the liver independently of the portal venous system; such veins communicate with intrahepatic portal branches to various degrees.
