Toxic intracerebral demyelination in a case of suicidal Cypermethrin poisoning

A 15 years old boy was admitted with history of suicidal pyrethroid compound 'cypermethrin' consumption. Subacute evolution of central nervous system manifestations and radiologically documented subcortical demyelination were observed. Gradual and partial recovery could be achieved with conservative treatment over few weeks. Although generally considered safe pyrethrin compounds can occasionally result in devastating neurological consequence as observed in this case.
