Liver metastasis from hepatoid adenocarcinoma of the stomach mimicking hepatocellular carcinoma: Dynamic computed tomography findings

Figure 2 Dynamic enhancing pattern of the liver metastasis from hepatoid adenocarcinoma of the stomach in a 69-yr-old male. A: Liver metastasis from hepatoid adenocarcinoma of the stomach presented with hypoattenuation on precontrast computed tomography (CT); B and C: The liver mass revealed arterial hyperattenuation (B) and late phase washout (C) on dynamic CT study. Central necrosis and tumor hemorrhage (arrow) were noted; D: The patient received total gastrectomy combined with systemic chemotherapy. Progression of the liver metastasis with direct IVC invasion (arrow) was observed on follow-up CT. Pre: Precontrast; A-phase: Arterial phase; PV-phase: Portal venous phase; F/U: Follow-up image.
