Focal Nodular Hyperplasia in the Caudate Lobe

Incidentally seen on a trauma CECT was a hyperdense with central low attenuation in the caudate lobe (first image). Further work up with MR re-identified the mass as isointense on T1WI, isointense with a hyperintense central scar on T2WI, and enhancement of the central scar on post contrast T1WI.  The findings are compatible with focal nodular hyperplasia.
