Figure 9a. MR imaging appearance of multiple FNH lesions. (a) Axial gadolinium-enhanced fat-saturated 3D fast GRE image obtained during the arterial phase shows intense homogeneous enhancement of two lesions (arrows). This finding is compatible with FNH. (b) Photomicrograph (original magnification, x200; H-E stain) of a biopsy specimen from one of the lesions shows classic FNH composed of nodules (*) with fatty infiltration (open arrow). Septa (curved arrow) surround the nodules and contain ductular proliferation, inflammatory infiltrates, connective tissue, and vessels.
