Dysembryoplastic neuroepithelial tumor (DNT)
If your child’s doctor suspects that he may have a dysembryoplastic neuroepithelial tumor, she may order diagnostic tests including:
- neurological exam– a test of your child’s reflexes, muscle strength, eye and mouth movement, coordination and alertness
- computerized tomography scan (also called a CT or CAT scan)– This is a diagnostic procedure that uses x-rays and computer technology to produce cross-sectional images (often called slices), of the brain and spinal cord. A CT scan will identify low-density dysembryoplastic neuroepithelial tumors.
- magnetic resonance imaging (MRI)– This is a procedure that uses large magnets, radiofrequencies and a computer to produce detailed images of your child’s organs and other bodily structures. It can help confirm the presence of a DNT and distinguish it from other types of tumors.
- immunohistochemical and ultrastructural studies- lab-based studies that can confirm the origin of DNT and help your child’s doctor determine the best treatment
