An 85-year-old woman, with a clinical history of previous surgical and percutaneous treatments for hepatocellular carcinoma, had periodic follow-up examinations. In post-treatment imaging surveillance, a contrast-enhanced multidetector computed tomography (MD-CT) scan was performed to evaluate the possible presence of new lesions and to study the hepatic vasculature. The examination revealed a new nodular lesion in the eighth hepatic segment that was consistent with hepatocellular carcinoma.
Image postprocessing for the hepatic arterial and venous vascular system was performed. Through MD-CT with volume rendering, reconstruction of the portal, splenic, and mesenteric vein system was unremarkable, with no vascular pathologies or anatomic variations (Fig. 1). Consequently, the patient underwent transarterial chemoembolization, with technical and clinical success.
