What is Ependymoma?

  • An ependymoma is a tumor that arises in the cells lining the ventricular system of the brain or spinal cord. The ventricles contain cerebrospinal fluid (CSF). Ependymomas can form in any of the ventricles in the brain or spinal cord, but most ependymomas arise in the fourth ventricle and affect the cerebellum and the brain stem.

    Ependymomas account for 5 to 10 percent of pediatric brain tumors and occur equally in boys and girls. These types of tumors are the third most common brain tumor in children. Though ependymomas rarely occur in the spinal cord, they do account for about 25 percent of all spinal cord tumors. Most patients with tumors of the spinal cord are older than 12.
