摘　　要：目的:分析脑膜瘤瘤周水肿的发生机制及MR表现。方法:搜集81例经手术、病理证实脑膜瘤,分析其瘤周水肿的MR表现。结果:①无水肿区,瘤周无明显异常信号。②圆晕状水肿,瘤周弧形晕带状异常信号。③不规则水肿,瘤中斑片状不规则异常信号。④指压迹状水肿,白质内指压迹状异常信号。结论:脑膜瘤瘤周水肿有一定特点,对其影像学诊断及手术方案的制定提供依据。Objective:Analyzing the mechanism and MR performance in meningioma.Methods:Collecting the MR data of 81 cases was confirmed by surgical operation, pathology, analyzing its peritumoral edema in MR performance.Results:①)Having no edema area, the peritumoral have no obvious and excrescent signal.②Edema with halo-like, the peritumor an arc-shaped with halo-like takes the excrescent signal in form.③Irregular edema, irregular and excrescent signal in a form in peritumor.④Finger-like edema, the white matter inside points to press the excrescent signal in form in vestige.Conclusion:Peritumoral edema in meningioma contain certain characteristics, as to it's image learns the establishment between diagnosis and surgical operation project offering help.
