Methyl iodide intoxication. A case report.

A 41-year-old chemist developed methyl iodide intoxication. His case is presented with a review of pertinent literature. Characteristics of the poisoning include a delay between exposure and onset of symptoms; early systemic toxicity with congestive changes in the lungs and oliguric renal failure; prominent cerebellar and Parkinsonian neurologic symptoms as well as seizures and coma in severe cases; and psychiatric disturbances that can last from months to years. Although methyl iodide is a rare form of intoxicant, its manifestations are similar to that of poisoning with the other monohalomethanes that are not uncommon.
