Frequent association of cortical dysplasia in dysembryoplastic neuroepithelial tumor treated by epilepsy surgery

We conclude that DNT is frequently associated with CD, with a wide area of epileptogenic activity that might be related to the presence of CD around the DNT. Comprehensive preoperative investigations for accurate localization of epileptogenic activity, meticulous brain mapping, and a rather radical resection of pathological areas might be essential for the achievement of excellent seizure control in DNT-associated epilepsy.
