Ependymal Tumors
Ependymal tumors usually begin in cells that line the spaces in the brain and around the spinal cord. These spaces contain cerebrospinal fluid, a liquid that cushions and protects the brain and spinal cord. Grades of ependymal tumors include the following:
- Grade I and grade II ependymomas: These ependymomas grow slowly and have cells that look very much like normal cells. They can often be removed completely by surgery.
- Anaplastic ependymoma (grade III): Anaplastic ependymomas grow very quickly.
