title: Ultrasonographic demonstration of inferior vena caval invasion.
abstract: Whenever a liver neoplasm is seen ultrasonographically, an effort should be made to visualize the veins within the liver as well as the inferior vena cava for tumor extension. Valuable information can be obtained by the demonstration of this finding which may radically alter the further work-up and treatment of the patient.
