In liver disease with hyperammonemia, the gray matter is diffusely swollen and may have restricted diffusion.

Main differential diagnosis (when the cortex is diffusely involved): anoxia, CJD.

FIGURE 18-43. Axial noncontrast T1 in a patient with liver insufficiency shows bright basal ganglia.

FIGURE 18-44. In a different patient, midsagit-tal T1 shows increased signal intensity in dorsal brain stem, midbrain, and adenohypophysis.

FIGURE 18-45. Axial FLAIR, in a different patient, shows high signal throughout the gray matter.
