WebOn MRI, the central scar in FNH is predominantly T2 hyperintense, whereas the scar in fibrolamellar HCC is typically T2 hypointense. However, rarely, fibrolamellar HCC may show a T2-hyperintense scar (especially those with a very vascular scar) and biopsy may be required if there is any doubt in the diagnosis [ 41 ]. WebAbstract. It is known that Focal Nodular Hyperplasia (FNH) of the liver is the second common benign liver tumor following hemangioma.
