Abdominal magnetic resonance images: (a) T1W, (b) arterial phase, and (c) portal phase. Focal hepatic lesion with lobulated borders and a 13 cms of diameter which has signal heterogeneity in T1 and T2 sequences, with restrictive regions in the diffusion sequence; the lesions are highlighted in the arterial phase; they are practically isointense in the portal and late phase. Irregular hypointense linear area which corresponds to a scar zone.
