Localizing value of epileptic ecstatic seizures in a patient with focal epilepsy due to temporal DNET

characterized by intense feeling of well-being and heightened self-awareness. The symptomatic zone in this type of seizures seems to involve the anterior insula. A 38-year-old man had a history of focal epilepsy since the age of 16, secondary to a left temporal mass lesion compatible with DNET (Dysembryoplastic neuroepithelial tumor). Few years later, he began to present seizures characterized by a feeling of sudden pleasure followed by brief loss of consciousness. Follow-up MRI remained stable. Intercritical EEG showed epileptiform discharges at T3-T5 with phase reversal at F7-T3. Despite video-EEG recording of seizures was not available, we discuss the localizing value of this seizure type as well as the complex and multifocal epileptogenesis of DNET even in the perspective of surgical therapy.
