Computed tomographic demonstration of "coronary" collateral vein calcification and patent spleno-renal shunt--a case report.

A case of hepatoma associated with previously treated portal hypertension and calcification of the portal veins, collaterals, and superior mesenteric veins was demonstrated by CT, as was the patent splenorenal shunt and ascites. Computed tomography successfully demonstrated all these aspects of the case by plain scans and the use of angiotomography with rapid sequential sections using the multiple bolus technique of contrast enhancement.
