目的:探讨嗅沟脑膜瘤的影像学表现与病理组织学之间的相关关系及其鉴别诊断。方法:对11例经手术及病理证实为嗅沟脑膜瘤的患者进行回顾性分析。男5例,女6例,年龄29~59岁,平均48岁。行CT检查3例,MRI检查8例,均为增强扫描。分析CT、MRI影像特征,并与手术、病理结果对照。结果:瘤灶起源于颅前窝嗅沟,多数密度或信号均匀,边界清楚,均匀增强;少数不均匀增强,大部分病例出现脑膜尾征,少数伴钙化、坏死、囊变。邻近颅骨受累时引起骨质增生或受侵。结论:起源于嗅沟的脑膜瘤均具有典型的影像学表现特征。嗅沟骨质及其脑膜影像改变的显示,对瘤灶起源具有重要的定位、定性诊断价值。MRI优于CT,但CT对钙化和骨质改变显示优于MRI。
