Myoclonus with electrocerebral silence in a patient receiving penicillin.
Multifocal myoclonus is a well-recognized complication of high doses of penicillin. In man, the site of origin of penicillin-induced myoclonus has not been clearly established, but there is evidence from animal studies that it may originate at a cortical, subcoritcal, or spinal level. We report a case of multifocal myoclonus occurring in a patient receiving large doses of penicillin. The myoclonus appeared when there was no clinical or EEG evidence of upper brain stem or cerebral function. The observations reported suggest that penicillin-induced myoclonus may occur in man and may originate at a caudal brain stem or spinal level.
