Ependymoma is a slowly growing tumor, that takes origin from cells of the ventricular wall or the epndymal canal. It affects preferentially children and jung adults. Histologically it belongs to the OMS type II classification. The anaplastic variant belongs to the OMS grade III. It represents the 6.12% of the intracranial tumors in infancy and the most frequent age of appearance is around 6 years without sex preference. In children is the third most frequent tumor of the posterior fossa, after medulloblastoma and astrocytoma. The biological behaviour of ependymoma varies after its location in the posterior fossa or the supratentorial room. The supratentorial ependymomoma has not a characteristic radiological pattern and is frequently anaplastic; however, because the total resection is possible, it can be cured in most cases. On the other hand, the posterior fossa ependymoma having a typical radiologic pattern, grows habitually from the floor of the fourth ventricle making impossible the total resection and therefore curation, even in low grade tumors. The elective treatment of ependymoma is total resection and, if not possible, it can be complemented with conformed local radiotherapy with linear acclerator, both for low or high grade tumors. Chemotherapy is ineffective in ependymomas.
