    Abstract:
    We encountered a patient with hepatocellular carcinoma who had discrepant imaging findings on portal vein thrombosis with portal phase dynamic computed tomography (CT) and CT during arterial portography (CTAP). CTAP, via the superior mesenteric artery and via the splenic artery, both showed a portal perfusion defect in the right hepatic lobe, indicating portal vein thrombosis in the main trunk of the right portal vein. Portal phase dynamic CT clearly depicted portal perfusion of the same hepatic area. Transarterial chemoembolization was successfully performed, but it was associated with severe liver injury. Clinicians should be cautious about this possible discrepancy based on imaging technique. The inaccurate evaluation of portal vein thrombosis may result in inappropriate treatment selection, which can worsen patient prognosis.
