Abstract
A retrospective review of the dynamic computed tomography (CT) and ultrasound scans from examinations of 134 patients with hepatocellular carcinoma was undertaken with emphasis on evaluation of hepatic vein involvement. Hepatic veins were involved in 8 patients (5.9%). Portal vein obstruction was associated in 7 of these cases. Sonography demonstrated hepatic vein involvement in 6 cases was considered within normal limits in 1 and failed to display hepatic veins in another. Dynamic CT was superior in depicting venous obstruction in all the cases by different signs including (a) hypodensity and enlargement of the vessel, (b) perivenous arterial hypervascularization surrounding the hypodense intraluminal region, and (c) hemokinetic changes in relation to the outflow obstruction. The frequency and significance of these CT signs are discussed and correlated in 2 patients with magnetic resonance imaging (MRI) data.Keywords
