2y FS Pug with recent onset of lethargy. There is regional marked T2 and FLAIR hyperintensity (a,c,d: arrowheads) and T1 hypointensity
(e,f: arrowheads) involving the frontoparietal cerebral cortex. Uncal (transtentorial) herniation (b: arrow), cerebellar herniation
(b: arrowhead), and interstitial edema (d: arrows) are also present. Widespread meningeal enhancement is seen following contrast
administration (f: arrows). Postmortem examination revealed meningitis and necrotizing encephalitis of gray and white matter
predominately in the cerebral hemispheres, consistent with necrotizing meningoencephalitis.
