4y FS Bengal cross with pelvic limb weakness. Multiple ill‐defined and variably sized T1 hypointense and T2 hyperintense foci are seen in
the piriform lobes and parietal cortex (a,b,d,e: arrows; additional lesions not shown). These focal lesions heterogeneously enhance and
have ill‐defined margins following contrast administration (c,f,g: arrows). Prominent multifocal meningeal enhancement is also seen
(f,h: arrowheads). Postmortem examination confirmed multisystemic inflammatory disease caused by Cryptococcus gattii. The chronic
inflammatory response in the meninges and brain was histiocytic and lymphoplasmacytic with intralesional fungal elements.
