摘　　要：目的分析鞍区脑膜瘤MRI影像学表现及鉴别诊断价值。方法回顾性分析本院2017年1月至2019年5月收治的45例鞍区脑膜瘤患者的临床资料,分析鞍区脑膜瘤的MRI表现及其诊断价值。结果45例鞍区脑膜瘤患者中,MRI检查共检出42例,检出准确率为93.33%;45例病例中与垂体分界明显的有29例,呈圆形或卵圆形,边界清楚;与垂体分界模糊的有11例,呈不规则形,边界不清楚。肿块宽基底,T_(1)WI上显示等信号,T_(2)WI上呈等或略高信号,明显强化。邻近脑组织受压位移,合并有不同程度脑水肿;增强扫描呈均匀或不均匀强化。结论MRI可显示鞍区脑膜瘤的影像学特点,具有较高的诊断准确率,在定性、定位诊断中具有重要价值。Objective To analyze the imaging features of MRI and its differential diagnosis value for meningioma in sellar region.Methods The clinical data of 45 patients with meningioma in sellar region admitted to our hospital from January 2017 to May 2019 were retrospectively analyzed,MRI features and diagnostic value of sellar meningioma were analyzed.Results Among 45 patients with meningioma in the sellar region,42 cases were detected by MRI,and the detection accuracy was 93.33%.Among the 45 cases in this group,there were 29 cases with obvious boundary with pituitary,which was round or oval,and the boundary was clear.And there were 11 cases with blurred boundary with pituitary,which was irregular and the boundary was unclear.The mass has a wide fundus.The equal signal is displayed on the T_(1)WI,and the signal is equal or slightly higher on the T_(2)WI,which is obviously enhanced.The adjacent brain tissue was compressed and displaced,and combined with different degrees of cerebral edema;enhanced scan showed uniform or uneven enhancement.Conclusion MRI can show the imaging characteristics of sellar meningiomas,which has a high diagnostic accuracy,and is of great value in qualitative and localized diagnosis.
