A beagle puppy was presented with clinical signs indicative of a cerebellar
disease. Histopathological evaluation of the cerebellum revealed a diffuse
degenerative cortical lesion. The clinical history and the histopathologic
al findings are consistent with a neonatal cerebellar abiotrophy. Furthermo
re, the breeding history supports the hypothesis of an inherited genetic di
sorder that is, most likely, an autosomal recessive trait.
