目的：加强对脑膜瘤囊性变的认识，提高诊断的准确性。方法对6例脑膜瘤囊性变病灶的MR表现进行分析。结果发生于大脑凸面及上矢状窦、大脑镰旁5例，小脑凸面1例；MR特征：T1及T2序列病灶的实性部分及囊壁均呈等或略低信号。DWI序列5例表现为高信号，1例表现为中等高信号。增强扫描表6例均有中等以上强化。病灶的囊性部分，T1序列均表现为低信号或略低信号，T2序列表现为高信号4例，高低混合信号2例。结论囊性变的脑膜瘤MR表现仍具有脑膜瘤特征性。
目的：加彊對腦膜瘤囊性變的認識，提高診斷的準確性。方法對6例腦膜瘤囊性變病竈的MR錶現進行分析。結果髮生于大腦凸麵及上矢狀竇、大腦鐮徬5例，小腦凸麵1例；MR特徵：T1及T2序列病竈的實性部分及囊壁均呈等或略低信號。DWI序列5例錶現為高信號，1例錶現為中等高信號。增彊掃描錶6例均有中等以上彊化。病竈的囊性部分，T1序列均錶現為低信號或略低信號，T2序列錶現為高信號4例，高低混閤信號2例。結論囊性變的腦膜瘤MR錶現仍具有腦膜瘤特徵性。

Objective To enhance the understanding of cystic meningioma, improve the accuracy of diagnosis. Methods MR findings of 6 cases of cystic lesions of meningioma were analyzed. Results 5 cases occurred in the cerebral convexity of superior sagittal sinus and falx, 1 case occurred in cerebellar convexity;MR feature:the solid part and cystic wall of T 1 and T 2 sequence lesions were isointense or slightly low signal. DWI sequence in 5 cases showed high signal, 1 case showed moderate to high signal. Enhanced scanning table 6 cases had moderate enhancement. Cystic part lesions, T 1 sequence showed low signal or slightly low signal on T 2, high signal sequence was found in 4 cases, 2 cases of mixed signal. Conclusion The MR findings of cystic meningioma has characteristic of meningioma.
