Postoperative Myoclonus After Epilepsy Surgery: A Case Report

Abstract

Accurate diagnosis of myoclonus after epilepsy surgery is important to determine the surgical outcome in patients with intractable epilepsy. Emerged bilateral myoclonus in a 53-year-old man after surgical resection for treatment of traumatic refractory epilepsy is reported. An electroencephalography correlate of the myoclonic jerks with cortical potentials was not observed. Treatment with clonazepam significantly reduced the myoclonic twitching. The possible mechanism and differential diagnosis between non-epileptic and epileptic myoclonus following brain surgery are discussed. To avoid misdiagnosis and ensure appropriate treatment, the origin of jerking mimicking epileptic myoclonus after brain surgeries needs to be carefully investigated.
