Calcification in caval membrane causing primary Budd-Chiari syndrome: CT demonstration.


We report two cases of membranous obstruction of the inferior vena cava (MOIVC) in which we observed patchy calcification in the membrane. The location of the calcification in the membrane was confirmed histologically. This finding was found histologically in four of eight cases of MOIVC, and it is a useful finding in the CT diagnosis of MOIVC.
