| 摘 要： | 目的:探讨脑膜瘤伴瘤周水肿的机制。方法:49例经手术病理证实的脑膜瘤,回顾性分析伴有瘤周水肿脑膜瘤的MRI特征,用Fisher′s检验比较肿瘤大小、部位、边缘、假包膜征及肿瘤T2WI信号与瘤周水肿发生的关系。结果:肿瘤边缘、假包膜征和肿瘤T2WI信号与脑膜瘤瘤周水肿发生明显相关,P值分别是0.016,0.004 和0.041。结论:脑膜瘤脑界面侵袭性模式和T2WI高信号是提示脑膜瘤发生瘤周水肿的因素。

| Abstract: | Objective:To analyze the MRI characteristics of meningiomas with perifocal edema and to explore the mechanism of perifocal edema.Methods:49 cases of meningioma confirmed by surgery and pathology were retrospectively reviewed.A correlative study was made between the tumor size,location,margin,pseudocapsule sign and signal intensity on T2WI with peritumor edema using the Fisher's exact test.Results:The margin of the tumor,pseudocapsule sign and signal intensity on T2WI were closely correlated with the occureence of the peritumor edema.The P value was 0.016,0.004 and 0.041 respectively.Conclusion:Invasive pattern of tumor interface of meningioma and hyperintensity on T2WI were indicative factors of meningiomas producing perifocal edema. |
