Focal nodular hyperplasia in a 14 year old female patient. The hepatic lesion is hypointense to background liver parenchyma on (a) pre-contrast T1-weighted fat-saturated sequences. There is avid enhancement of the lesion post gadobenate dimeglumine administration in (b) the arterial phase, with eventual homogenous enhancement of the lesion and central scar in the (c) portal venous and (d) equilibrium phases. The delayed (e) 30 min and (f) 45 min images show the lesion enhancing to a similar intensity as the background liver parenchyma
