Pseudolesion in segment IV of the liver with focal fatty deposition causedby the parabiliary venous drainage

A case with a pseudolesion associated with focal fatty deposition in segmen t TV of the liver observed on conventional CT and CT during arterial portog raphy caused by the parabiliary venous drainage is presented. Close observa tion of the common hepatic angiography was helpful to recognize this unusua l vessel as a cause of this pseudolesion. Selective catheterization of the posterior superior pancreaticoduodenal artery and CT during its venous phas e confirmed the etiology of the pseudolesion. (C) 2000 Elsevier Science Ltd .
