Ependymomas<\/strong> are primary tumours that originate in the ependymal cells, cells that surround ventricular brain cavities and the central canal of the spinal cord. They are included in the group of gliomas<\/strong>.<\/p>\n

They represent between 5-10% of neuroepitelial tumours and are especially common among children. 70% of intracranial ependymomas appear in children. They present two peaks of incidence, one at 5 years of age, where they are especially common at a level of the IV ventricle and at 35 when they are more common on a spinal level.<\/p>\n

It is the most frequent tumour of the fossa posterior in children, after meduloblastomas<\/strong> and astrocytomas<\/strong>.<\/p>\n

\"Ependinomas\"The clinical appearance is common to all other brain tumours, with headache, nausea and vomiting being frequent symptoms of cerebral ependymomas, in many cases due to obstruction of the normal circulation of cerebrospinal fluid (hydrocephalus). In the event de spinal tumours, they may simulate sciatica or clinical deficiency due to spinal compression, paraparesis, tetraparesis in cervical cases, etc.<\/p>\n

The WHO classifies ependymomas<\/strong> in four groups.<\/p>\n
