Cerebellar cortical atrophy in a puppy.

A description is given of the history and neuropathology of a mongrel puppy which had suffered from cerebellar cortical atrophy. The condition was attended by intractable cerebellar ataxia and characterised by selective degeneration of the Purkinje cells of the cerebellar cortex. Cerebellar dysfunction is briefly reviewed. The lesion and possible aetiology are briefly discussed.
