摘要
目的探讨小脑幕脑膜瘤MRI表现及对临床的应用价值。方法回顾性分析8例经病理证实的小脑幕脑膜瘤病例的MRI表现。结果小脑幕脑膜瘤可发生在小脑幕的任何部位,具有脑外肿瘤特点;幕下5例,幕上1例,幕下及幕上都有2例;MRI能准确判断肿瘤位置,位于幕上、幕下和肿瘤具体附着部位。结论小脑幕脑膜瘤有MRI特征表现,MRI多序列、多方位检查对于小脑幕脑膜瘤能提供更多的诊断信息。
Objective To discuss MRI appearance and its clinical application value of tentorial meningiomas. Methods MRI findings of tentorial meningiomas in 8 cases confirmed by pathology were retrospectively analyzed. Results Tentorial meningiomas can occur in any part of the tentorium, having the characteristics of extracerebral tumors;5 cases under the tentorium cerebelli, 1 case on the tentorium cerebelli, and 2 cases both infratentorium and supratentorium. MRI can accurately determine the tumor location, on or under the tentorium cerebelli and specific parts attached. Conclusion There are MRI appearance characteristics of tentorial meningiomas, It can provide more diagnosis information of tentorial meningiomas with MRI multiple sequence and directional.
