The authors conducted a retrospective examination of 62 hepatocellular carcinomas, taking dynamic CT scans of selected sections after an intravenous contrast bolus. The proximal portal vein was involved in 40% of cases and distal segment in 16%. Angiographic correlation was available in 23 patients. The characteristic appearance of tumor within the portal vein was noted in many cases; in others, distinction between tumor and bland thrombus could not be made. Peripheral portal vein obstruction was suggested when a small, hypervascular tumor became hypodense during the portal phase of CT. The frequency and significance of these CT signs of portal vein involvement are discussed.
