Case No. 1: detection by gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid magnetic resonance imaging and computed tomography arterioportal angiography. Imaging and histological findings of the nodule in segment eight. A: Ultrasonography (US) reveals a 12 mm hyperechoic nodule (arrow); B: Gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid magnetic resonance imaging reveals a defect (arrow) in the hepatobiliary phase; C, D: Computed tomography during arteriography reveals isodensity (C) and computed tomography during arterial portography (D) reveals a perfusion defect (arrow); E: The nodule is diagnosed as moderately-differentiated hepatocellular carcinoma by US-guided biopsy.
