Types of Brain Tumors
An ependymoma usually begins in cells that line the spaces in the brain and around the spinal cord. These spaces contain cerebrospinal fluid, which is a liquid that cushions and protects the brain and spinal cord. These types of brain tumors are most commonly found in children and young adults.

Oligodendroglioma is a rare tumor that arises from cells that make up the fatty substance that covers and protects nerves. These tumors usually occur in the cerebrum. Oligodendroglioma grow slowly and usually do not spread into surrounding brain tissue. These tumors are most common in middle-aged adults.
Mixed gliomas are brain tumors that contain more than one type of cell. The prognosis for this kind of brain tumor will depend on the cell type and the highest grade present in the tumor.
Brain tumors that do not start in the glial cells include:
- Germ cell tumor of the brain
- Pineal region tumor.
A medulloblastoma usually arises in the cerebellum. This brain tumor type forms from abnormal brain cells at an early stage in development. Medulloblastoma is the most common brain tumor in children. It is sometimes called a primitive neuroectodermal tumor. This tumor may spread from the brain to the spine through the cerebrospinal fluid.
