Overview

NCI Definition: A WHO grade II, 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) [1]

Ependymomas most frequently harbor alterations in CHEK2 and ARID1B [2].
