摘　　要：目的:通过研究脑膜瘤的MRI表现,探讨脑膜瘤瘤周水肿(peritumoral brain edema,PTBE)与脑膜瘤部位的关系。方法:对106例行MRI检查的脑膜瘤患者进行回顾性研究。分析脑膜瘤位置,测量脑膜瘤体积及PTBE体积,计算水肿指数(edema index,EI),并对PTBE形状进行分类,采用SPSS13.0软件对数据进行统计分析。结果:不同部位脑膜瘤其PTBE的发生率存在差异,位于大脑凸面、矢状窦旁、前颅窝底的脑膜瘤PTBE较其他部位为高。位于大脑凸面、矢状窦旁存在瘤周水肿的脑膜瘤EI未见明显增高。不同部位发生瘤周水肿的脑膜瘤其PTBE的形状未见明显差异。结论:不同部位的脑膜瘤其PTBE发生率及EI均不同,PTBE形状与脑膜瘤位置无明显关系。Objective：By studying the performance of MRI of meningiomas,the correlation between the peritumoral edema and location of meningiomas was analyzed.Material and Methods： A retrospective study of 106 intracranial meningioma patients who underwent surgical removal of the tumor was performed.The tumor location,size,the PTBE size,edema index（EI=（Vedema＋Vtumor） /Vtumor） and the PTBE shape were determined by MRI.The SPSS 13.0 were performed to evaluate the PTBE and edema index.Results： Facies convexa cerebri,frontobasal and parasagittal meningiomas showed a significant increase in the edema incidence.Edema index of facies convexa cerebri and parasagittal meningiomas showed no significant increase.The shape of PTBE of meningiomas in different parts is not significant different.Conclusion： The PTBE and EI of meningiomas in different parts are different.The shape of PTBE of meningiomas in different parts is not significant different.
