Abdominal magnetic resonance imaging (MRI) findings: (a) T1-weighted image shows that the lesion is slightly hypointense with the central scar appears more significant hypointense (arrow); (b) T2-weighted images shows the same lesion as slightly hyperintense; (c) after enhancement, the signal of the lesion is markedly increased and appears hyperintense during the arterial phase except for the central area in fat-saturated T1-weighted image; (d) in the portal venous phase, the lesion is slightly hyperintense compared to the normal liver tissue and the central scar is poorly recognized.
