Signs and symptoms of ependymomas are related to the site of origin of the tumor.
Symptoms may be present for up to 12 months prior to diagnosis (depends on tumor location and grade). In general though the history is longer than for a rapidly growing tumor like medulloblastoma.
Supratentorial ependymomas are generally diagnosed a little earlier than posterior fossa tumors.
