CT evaluation of atypical hepatic fatty metamorphosis.

Focal fatty metamorphosis of the liver is a well-recognized entity characteristically demonstrated by a nonspherical, low-density area without mass effect. We present a case of focal fatty metamorphosis of the liver that shows multiple areas of low attenuation within the liver with mass effect. Radionuclide liver-spleen scan shows multiple focal defects corresponding to the areas of fatty metamorphosis.
