Ependymoma
A WHO grade 2, slow growing tumor of children and young adults, usually located intraventricularly. It is the most common ependymal neoplasm. It often causes clinical symptoms by blocking cerebrospinal fluid pathways. Key histological features include perivascular pseudorosettes and ependymal rosettes. (WHO)

class Information
ALT_DEFINITION
- A malignant neoplasm arising from ependymal cells that line the ventricles of the brain and the central canal of the spinal cord.
- A type of brain tumor that begins in cells lining the spinal cord central canal (fluid-filled space down the center) or the ventricles (fluid-filled spaces of the brain). Ependymomas may also form in the choroid plexus (tissue in the ventricles that makes cerebrospinal fluid).
