title: [Radiation-induced meningioma].
abstract: Meningiomas are neoplasms derived from arachnoid cells with their origin linked to idiopathic genetic abnormalities (deletion of the long arm of chromosome 22), predisposing diseases and radiotherapy induction. We report the case of a 50 years-old man radiation-induced meningioma 20 years after the diagnosis, surgical and radiation treatment of an oligodendroglioma. The supporting diagnostic criteria of radiation-induced meningiomas are discussed and the pertinent literature of the theme is revised.
