There are many different types of benign and malignant brain and spinal tumors. They are usually categorized by either the type of cell where the tumor begins or the area of the brain or spine where they occur. Ask your treatment team for more information about a specific type of brain or spinal tumor. Be aware that different names are sometimes used for the same type of tumor; the most common types include the following:

Gliomas Ependymomas Optic nerve glioma Brain stem glioma or cerebellar glioma Oligodendroglioma Oligoastrocytoma Low grade astrocytoma Anaplastic Astrocytoma (AA) Gliobastoma Multiforme (GBM)   Craniopharyngioma   Germinomas   Medulloblastomas   Meningiomas   Metastatic tumors   Pituitary tumors   Primary Central Nervous System Lymphoma   Primitive neuroectodermal tumors (PNET)   Schwannomas   Pineal region tumors

Primitive neuroectodermal tumors (PNET) PNETs can occur anywhere in the central nervous system (brain and spine), although the most common place is in the cerebellum. When they occur here, they are known as medulloblastomas. PNET symptoms depend upon actual location, but typically the patient experiences increased intracranial pressure and seizures. These tumors are fast growing and often malignant, occurring most often in very young children. It is believed these tumors arise from primitive, undifferentiated cells. Surgical debulking is typically the first line of treatment, followed by radiation and chemotherapy. Radiation is usually not recommended for children under three years of age.

Childhood Brain Tumors
Pediatric brain tumors affect nearly 1,500 to 2,000 children in the U.S. every year. They are diagnosed most often between the ages of three and eight, but can occur at any age.

Children with brain tumors are diagnosed and treated by our partner, Children's Memorial Hospital's Falk Brain Tumor Center. One of the first institutions in the country to develop a cohesive, multidisciplinary program for brain tumor treatment, Children's Memorial treats over 67 percent of children in the Chicago area who are newly diagnosed with this condition, and treat many additional patients with recurrent disease.
