Fig. 1.
Liver dynamic CT showed a hypervascular mass (arrows) with a size of 2.5 cm at the second hepatic segment. (A) In the arterial phase, strong contrast enhancement with central low density was observed. (B) In the portal phase, the tumor had almost washed out the contrast agent, but weak contrast enhancement still remained.

Liver magnetic resonance image reveals a capsulated mass (arrows) with a size of 2.5 cm. The mass shows low signal in the T1-weighted image (A), intermediate signal in the T2-weighted image (B), high enhancement at the arterial phase (C), and iso-signal in the diffusion-weighted image (D).
