The peripheral polyneuropathy has rarely been reported following carbon monoxide intoxication, and the precise pathogenesis remains in doubt. This report concerns a man who suffered from severe carbon monoxide intoxication, and resulting in the development of a peripheral polyneuropathy with polyradiculopathy.

The electrodiagnostic study showed abnormal resting potentials on electromyogram, normal to subnormal range of nerve conduction velocity with reduced amplitude, and evidence of polyradiculopathy.
