Normal branching of hepatic vein is not seen, rather a longitudinal thin partition/web is seen in suprahepatic inferior venacava, extending upto anatomical level of origin of hepatic veins. Associated ascites and splenomegaly is seen, with prominent portal vein. Caudate lobe enlargement is also marked.
