Dysembryoplastic neuroepithelial tumor (DNT)
Who is at risk for a DNT?
A DNT usually begins in children and teenagers who are 20 years old or younger.
What are the symptoms of dysembryoplastic neuroepithelial tumor (DNT)?
While each child may experience symptoms differently, and symptoms may vary depending on the size and exact location of the tumor, the most common symptom for DNT is the presence of seizures that are difficult to control with anti-seizure medication. In fact, it’s not uncommon for children to have their first seizure before age 10 and then continue to experience them for several years before the diagnosis is made.
DNT tumors are found in the cerebrum, which is the part of the brain that controls thought, movement and sensation, so your child may experience other symptoms that relate to those functions.
What is a DNT made of?
These tumors consist of different types of abnormal cells including:
- oligodendrocytes (cells that provide support and nourishment for cells that transmit nerve impulses)
- astrocytes (connective tissue cells)
