目的：探讨脑膜瘤的MRI表现特征，以提高对该病诊断的准确性。方法选取江苏溧阳市中医院14例经手术及病理证实的脑膜瘤患者的临床及MRI资料进行回顾性分析。结果14例患者中肿瘤位于顶部大脑凸面的5例，前颅底3例，后颅底1例，大脑镰旁5例。MRI信号特点：脑膜瘤在T1 WI上6例呈等信号，8例为低信号，其中4例信号不均匀，T2 WI上7例呈稍高信号，3例呈低信号，4例呈混杂信号，信号不均匀的病例可伴有低信号的血管流空新号或囊状高信号。增强后14例病灶均明显强化，其中有4例强化不均匀。8例可见明显脑膜尾征，6例肿瘤周围显示水肿带，5例在病灶周围可见环状低信号。结论 MRI对脑膜瘤的诊断，不仅能提供其在三维空间上的形态、大小和所处位置，并且通过脑膜瘤的特异性MIR信号和征象作出定性诊断，具有重要的临床应用价值。

Objective To study the character of magnetic resonance imaging(MRI)of meningoma.Method Retrospective analysis on the clinical and MRI data of 14 cases of meningoma patients who were conifrmed by surgery and pathology.Results For 14 cases, meningoma of 5 cases is available at top cerebra convexity; That of 3 cases, front skull base; That of 1 case, back skull base; And that of 5 cases, falx cerebri. All cases are those with single lesion. Character of MRI signal: Equation and slight low signal were dominant for meningoma with T1WI. Thereinto, 6 cases show equation signal; 6 cases, low signal; 4 cases, unequal signal with lfake or vesica-type low signal image; And 5 cases, loop low signal around the lesion. Regarding meningoma with T2WI, 7 cases show slightly high signal; 3 cases, low signal, and 4 cases, mixed signals, with low-signal blood vessel lfow void image and vesica-type high signal image. After enhancement 14 cases of lesion were obviously enhanced. However, 4 cases saw unequal reinforcement; 8 cases, apparent dural tail sign, and 6 cases, oedema section around the tumor.Conclusion Diagnosis on meningoma by MRI could not only show shape, size and location in a three-dimensional perspective, but also give judgement by virtue of typical MRI signal and tail signal, which plays an important role in clinical application.
