Hepatocellular carcinoma composed of two different histologic types imaging features on gadoxetic acidenhanced liver MRI

Abstract

In gadoxetic acid?enhanced liver magnetic resonance imaging(MRI), it is known that the pseudoglandular type of hepatocellular carcinoma (HCC) may demonstrate high signal intensity on 20-minutes delayed imaging unlike the microtrabecular counterpart. Herein we report a case of HCC which consisted of mixed components of hypo- and hyper-intensity in the hepatobiliary phase of gadoxetic acid-enhanced MRI, focusing on its imaging findings and pathologic features.
