What is an ependymoma?

Ependymoma is a type of glioma that develops from ependymal cells. Ependymomas usually develop in the lining of the ventricles or in the spinal cord. The most common place they are found in children is near the cerebellum. The tumor often blocks the flow of the cerebral spinal fluid (CSF), causing increased intracranial pressure.

Ependymomas are rare, accounting for just 2-3% of primary brain tumors. However, they account for about 8-10% of brain tumors in children. They most often occur in children younger than 10 years of age.
