title: [Radiation-induced meningiomas of the brain].
abstract: From the observation over 62 patients with meningioma of the brain a connection was detected between previous X-ray irradiation of the skin on the head and the occurrence of the meningioma. Predominance of parasagittal localization of the tumors was revealed which, evidently, was associated with the peculiarities of the method of X-ray therapy applied and with the possibility of the growth of the meningiomas from arachnoid-endothelial aggregations in the dura mater. Multiple meningiomas were encountered in 23% of the patients. The cases are described.
