Dysembryoplastic neuroepithelial tumors (DNTs) commonly abbreviated DNT or DNET was first coined by Daumas-Duport and colleagues to describe a cortical lesion presenting in childhood 1).. These tumors are most often identified and diagnosed in patients under 20 years old. All patients had seizures with age at onset ranged from 7 to 27 years. symptoms of dej´ a-vu and visceral aura followed by short` loss of awareness without automatisms. Typically these tumors are diagnosed in children or young adults, as a result of the investigation of seizures, which have usually had childhood onset. Introduction The term dysembryoplastic neuroepithelial tumor (DNET) was first described in 1988 by Dauport et al1 to describe a unique histological pattern of brain tumors associated with medically intractable partial seizures which are surgically curable. When a tumor grows into or presses on an area of the brain, it may stop that part of the brain from working the way it should. In children, DNTs are considered to be the second leading cause of epilepsy. Prayson RA, Morris HH, Estes ML, Comair YG.
