Focal Nodular Hyperplasia : Imaging

Comments:
The diagnosis of focal nodular hyperplasia (FNH) of liver can be accurately done in most cases with contrast-enhanced CT or MRI study. This CT with contrast (coronal view) shows a large, partially exophytic mass in the liver with bright contrast enhancement in the arterial phase. The darker non-enhancing area within the lesion is the central scar.
