Tumors, particularly low grade glioma and glioneuronal tumors, account for 25-35% of patients who are undergoing epilepsy surgery for intractable seizures. A comprehensive epilepsy evaluation including video-electroencephalography (EEG) monitoring is useful for most of these patients, to determine the optimal extent of resection for the achievement of seizure-free outcome without causing postoperative deficits. Video-EEG monitoring for patients with brain tumor should also be considered in specific situations, such as patients with new postoperative seizures or advanced tumors with unexplained mental status change.
