Severe myoclonus in a patient recovering from falciparum malaria

Isolated myoclonus has rarely been reported as a complication of Plasmodium falciparum malaria. We describe the development of chaotic myoclonic jerks in an afebrile and conscious patient, the fourth day of treatment with quinine for P. falciparum infection. The myoclonus finally resulted in a generalized tonic-clonic seizure and coma, which resolved without further antimalarial treatment.
