6y M Rhodesian Ridgeback with a 4‐day history of signs referable to cerebellar disease. There is a poorly margined, T1 isointense and T2
hyperintense region in the vermis and left hemisphere of the cerebellum (a,b: arrowheads), which is not associated with any significant
mass effect. No enhancement of the lesion is seen following contrast administration. A fluorescent antibody test yielded a titer consistent
with active Neospora infection. A postmortem examination performed approximately 3 months after initial diagnosis confirmed a
diagnosis of necrotizing granulomatous cerebellitis with intralesional protozoa consistent with Neospora.
