A dysembryoplastic neuroepithelial tumor (DNET or DNT) is a low-grade, slow-growing brain tumor. It is a glioneuronal tumor, which means it contains properties of both glial cells (responsible for providing the structural support of the central nervous system) and neuronal cells (the functioning component of the central nervous system).

  • DNET often causes seizures that don’t respond to medication.
  • DNET occurs in the tissues that cover the brain and spinal cord.
  • A DNET usually begins in children and teenagers who are 20 years old or younger.
