Pseudolesion in segment IV of the liver with focal fatty deposition caused by the parabiliary venous drainage.
A case with a pseudolesion associated with focal fatty deposition in segment IV of the liver observed on conventional CT and CT during arterial portography caused by the parabiliary venous drainage is presented. Close observation of the common hepatic angiography was helpful to recognize this unusual vessel as a cause of this pseudolesion. Selective catheterization of the posterior superior pancreaticoduodenal artery and CT during its venous phase confirmed the etiology of the pseudolesion.
