During the same year (1984), we have seen 3 cases of meningiomas following radiation therapy of the brain for previously diagnosed tumors. A causal relationship between irradiation and meningioma has been postulated. Nevertheless, the coincidental occurrence in same patient of two different histological lesions is possible. The neoplasms developed after irradiation are of mesenchymal origin; they are fibrosarcomas, osteogenic sarcomas and meningiomas.
同年（1984年），我们见到3例在先前诊断的肿瘤接受脑部放射治疗后发生的脑膜瘤。有人推测放射与脑膜瘤之间存在因果关系。然而，同一患者身上巧合地出现两种不同组织学病变是有可能的。放射后发生的肿瘤起源于间充质；它们是纤维肉瘤、骨肉瘤和脑膜瘤。
