| 摘 要： | 目的 分析翼腭窝神经鞘瘤的CT和MRI表现. 资料与方法 回顾性分析12例经组织学证实的翼腭窝神经鞘瘤的影像学资料. 结果 12例神经鞘瘤均为单侧发病,病变以翼腭窝为中心生长并向其通道及周围间隙蔓延,边界清楚,呈卵圆形8例,梭形4例.CT表现:翼腭窝扩大,相应骨质受压变薄、移位及吸收;平扫显示10例病变密度均匀,另2例病变内可见低密度区,5例行CT增强扫描,其中3例病变显示不均匀强化.MRI表现:与脑实质比较,T1WI均呈等信号;T2WI呈等信号9例,高信号3例,10例病灶内可见点、片状高信号,其中5例并可见结节状高信号;增强后不均匀强化,T2WI上所见的高信号区均未见明显强化,其他区域中度或显著强化. 结论 根据典型的骨质及信号改变,可提示本病诊断.
