A 23-year-old male patient who had been diagnosed with cryptogenic cirrhosis 30 months earlier presented with a tumorous lesion in the liver that increased in size from 4 to 11 mm in the past 15 months. Contrast-enhanced computed tomography (CT) demonstrated a 1.1 cm-sized nodule in segment 4 of the liver with arterial hyperenhancement (Fig. 1A) and delayed phase washout (Fig. 1B), compatible with typical features of hepatocellular carcinoma (HCC). The nodule showed hypointensity with hyperintense central foci on a T2-weighted image (Fig. 1C) and subtle hyperintensity on T1-weighted magnetic resonance imaging (MRI) (Fig. 1D). After the injection of gadoxetic acid, strong homogeneous arterial enhancement without washout appearance (Fig. 1E) and hyperintensity on the transitional phase image were present (Fig. 1F). On the 20-minute hepatobiliary phase (HBP) image, the nodule showed hyperintensity with central hypointensity (Fig. 1G). There were no areas of diffusion restriction on a diffusion-weighted image (b = 800 s/mm2) (Fig. 1H). The lesion was pathologically diagnosed as a focal nodular hyperplasia (FNH)-like nodule arising from cryptogenic cirrhosis (Fig. 2).
