A case of collision tumors occurring between two distinct primary brain tumors is reported. A 61-year-old female without history of radiotherapy or phakomatosis presented with progressive ly increasing headache and left hemiparesis. Investigation revealed a meningioma and a Grade II astrocytoma in the right frontal lobe. Simultaneous development of a meningioma and a low-grade glioma at adjacent sites is extremely rare. This is the third case reported in the literature. Some hypotheses are proposed to explain this phenomenon but most likely represent a coincidental event.

报告了一例发生在两种不同原发性脑肿瘤之间的碰撞瘤病例。一名61岁女性，无放疗或神经皮肤综合征病史，出现进行性加重的头痛和左侧偏瘫。检查发现右侧额叶有一个脑膜瘤和一个二级星形细胞瘤。脑膜瘤和低级别胶质瘤在相邻部位同时发生极为罕见。这是文献报道的第三例。提出了一些假说来解释这一现象，但很可能是一个巧合事件。
