A 45-year-old man with a segment VI lesion. A: The lesion demonstrated a high signal on T2 weighted image; B: High on diffusion-weighted imaging; C: Low on volumetric interpolated breath-hold examination; D: Non-rim arterial-phase hyper-enhancement on arterial-phase image; E: Washout on portal phase. If we applied Liver Imaging Reporting and Data System (LI-RADS) criteria, the erroneous diagnosis of hepatocellular carcinoma could be made. However, the patient did not meet the at-risk criteria to apply LI-RADS. Histologic examination of the lesion demonstrated metastatic hemangiopericytoma; F: Magnetic resonance imaging of the brain, axial post-contrast T1-weighted image showed an extra-axial lobulated, occipital enhancing mass corresponding to recurrence of hemangiopericytoma 12 mo after total surgical excision.
