摘　　要：目的探讨磁共振成像在鞍旁脑膜瘤的MR表现特征及诊断价值。方法收集30例经临床、影像及手术病理证实的鞍旁脑膜瘤病例的MR常规平扫及增强扫描图像资料,分析鞍旁脑膜瘤病灶部位、形态及信号特征。结果MR平扫、增强发现30例鞍旁脑膜瘤,发生部位单发于一侧鞍旁海绵窦26例(累及同侧眼眶4例,累及翼腭窝3例),发生于双侧鞍旁海绵窦1例,颅内多发脑膜瘤合并一侧海绵窦脑膜瘤3例。结论应用合适的扫描技术,尤其是增强冠状位MR能很好的显示鞍旁脑膜瘤的发生部位、病灶大小、范围、信号特征,对周围邻近结构的累及状况,为临床手术和放疗定位提供准确的诊断依据。Objective To study the imaging feature and diagnosis value of parasellarr meningioma in MR.Methods Thirty cases of parasellar meningioma with pathologically proved or by clinical data proved were examed by MR plan scans and contrast scans,we study the position,shape,the imaging feature in MR of parasellar meningioma.Results All patients examined by MRI,26 cases were one side cavernous sinus(4 cases were invaded same side orbital,3 cases were involved pterygopalatine fossa),1 case was two side parasellar men...
