(ĕ-pen'di-mō'mă),
A glioma derived from relatively undifferentiated ependymal cells, comprising approximately 1-3% of all intracranial neoplasms; ependymomas occur in all age groups and may originate from the lining of any of the ventricles or, more commonly, from the central canal of the spinal cord; histologically, the neoplastic cells tend to be arranged radially about blood vessels, to which they are attached by means of fibrillary processes.
