SummaryDeafness and peripheral neuropathy are relatively rare complications of carbon monoxide intoxication. A case of carbon monoxide intoxication is presented with bilateral hearing loss and tinnitus, weakness and sensory impairment in the left hand, and weakness and atrophy of the left quadriceps femoris and hamstring muscles.Audiograms showed hearing loss of the perceptive type followed by partial improvement. Electromyograms revealed a neurogenic pattern and motor nerve conduction velocity was decreased in both legs.The etiology of the deafness and peripheral neuropathy in this case is not clear but is suspected to be due to combination of toxicity, hypoxia and compression.
