Two hundred patients with supratentorial glioma; astrocytoma (pilocytic, fibrillary, gemistocytic) 82, mixed glioma (oligoastrocytoma) 46, oligodendroglioma 8, malignant (anaplastic) astrocytoma 33 and glioblastoma multiforme 31, surgically treated for the tumours and followed up for one to sixteen years, were retrospectively analysed for the incidence of pre and postoperative epileptic seizures. 122 patients (61%) had seizures preoperatively. 62 (50.8%) of them had at least one or more seizures during follow up. Seizures were persistent in 22 patients. Doubtful, or one or two minor seizures occurred in 19 cases. Six patients in this group had seizure only at the time of CT confirmed recurrence, after a seizure free interval of one to nine years. Amongst 78 patients who did not have seizures preoperatively, 24 (30.6%) developed seizures during the postoperative follow up period. Recurrent attacks were reported only by 5 patients while 15 patients had seizure(s) only at the time of recurrence of tumour. Two patients had a few seizures in the early postoperative period and none thereafter, while doubtful seizures were reported by two patients.
