Chronic relapsing polyradiculoneuritis in a cat.

An 18 month old cat had a 6 month history of abnormal high stepping gait, ataxia, muscle twitching and loss of sensory perception. The clinical course was interrupted by several episodes of temporary remission. The essential pathological features were those of a polyradiculoneuritis with segmental demyelination, focal mononuclear cell infiltration and hypertrophic onion-bulb formations. The condition is compared with chronic relapsing polyradiculoneuritis in the dog and in man.
