CT scan axial images (a-c) showing a hypodense liver mass in the right lobe, which demonstrated significant enhancement in the arterial phase and peripheral rim enhancement in the delayed phase. MR images (d-g), T1-weighted image (d): lesion shows well circumscribed, heterogeneous, and hypointense masses. T2-weighted axial image (e) shows well-circumscribed, high signal intensity masses. On enhanced MR images, lesions show significant enhancement and tumor lobulation in the early arterial phase (f), enhancement in the 5 min delayed image (g)
