title: [Radiation-induced meningioma 20 years after operation and high-dose irradiation of an ependymoma].
abstract: We report the case of a 30 year old female patient who had got high-dose irradiation at the age of 10 after subtotal removal of an ependymoma in the fourth ventricle. 20 years later a meningioma of the tuberculum sellae was diagnosed and removed surgically. In this case the following meningioma fulfills the criteria for a radiation-induced tumor. There exist many reports about tumors of the central nervous system which have developed after radiotherapy in the irradiated field after a latency period. But after a thorough review of the international literature about radiation-induced tumors of the CNS is this the third case in which a benign meningioma has followed a radiotherapy for an ependymoma.
