Diagnostic procedures for a ganglioglioma may include: 

  • physical examination - the child may demonstrate evidence of increased pressure in the brain
  • computerized tomography scan (also called a CT or CAT scan) - a diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images (often called slices), both horizontally and vertically, of the body. CT scans are more detailed than general x-rays. For ganglioglioma, a CT scan of the brain is usually done.
  • magnetic resonance imaging (MRI) - a diagnostic procedure that uses a combination of large magnets, radiofrequencies, and a computer to produce detailed images of organs and structures within the body. For ganglioglioma, an MRI of the brain and spine is usually done, however gangliogliomas of the brain rarely spread to the spine.
  • electroencephalogram (EEG) - for children experiencing seizures, this procedure records the brain's continuous, electrical activity by means of electrodes attached to the scalp, and helps identify and localize seizure activity to a particular section of the brain
  • biopsy -a tissue sample from the tumor will be taken through a needle during a simple surgical procedure performed by a surgeon to confirm the diagnosis
