Ependymoma is a rare type of glioma that arises from ependymal cells lining the ventricles of the brain and the central canal of the spinal cord. It can occur at any age but is more common in children (intracranial) and in adults (spinal). Ependymomas can be benign or malignant depending on the grade and subtype.
WHO classification includes:
Grade I: Subependymoma, Myxopapillary ependymoma
