Abstract

In an adult white-tailed deer affected by polioencephalomalacia the lesions were acute ischemic-type necrosis, malacia, and hemorrhage in the cerebral cortex, vestibular nuclei, caudal colliculi, oculomotor nuclei, geniculate nuclei, thalamus, and ventral portion of the cerebellar vermis. The deer also had granulomas associated with Pneumostrongylus tenuis in the spinal leptomeninges.
