Fibrolamellar HCC. (a) Axial T2w image. In left lobe slightly well delineated mass (arrows) with heterogeneous central area. (b–d) In dynamic evaluation after Gd-BOPTA the lesion appears markedly heterogeneous hypervascular in arterial phase (c); it shows rapid and progressive wash out in portal phase. The central area is hypointense. Note complete thick pseudocapsule at the periphery (arrowhead). (e) In hepatobiliary phase image the lesion is hypointense; the central fibrotic component retains contrast agent.
