目的:探討嗅溝腦膜瘤的影像學表現(xiàn)與病理組織學之間的相關關系及其鑒別診斷。方法:對11例經手術及病理證實為嗅溝腦膜瘤的患者進行回顧性分析。男5例,女6例,年齡29～59歲,平均48歲。行CT檢查3例,MRI檢查8例,均為增強掃描。分析CT、MRI影像特征,并與手術、病理結果對照。結果:瘤灶起源于顱前窩嗅溝,多數(shù)密度或信號均勻,邊界清楚,均勻增強;少數(shù)不均勻增強,大部分病例出現(xiàn)腦膜尾征,少數(shù)伴鈣化、壞死、囊變。鄰近顱骨受累時引起骨質增生或受侵。結論:起源于嗅溝的腦膜瘤均具有典型的影像學表現(xiàn)特征。嗅溝骨質及其腦膜影像改變的顯示,對瘤灶起源具有重要的定位、定性診斷價值。MRI優(yōu)于CT,但CT對鈣化和骨質改變顯示優(yōu)于MRI。
