摘　　要：目的分析空蝶鞍的MRI表现，加深对本病的认识。方法对我院作垂体MRI检查资料完整的92例空蝶鞍病例进行回顾性分析。结果蝶鞍呈球形扩大45例。鞍内呈脑脊液信号且与鞍上池相通，垂体变薄紧贴鞍底或鞍背，信号均匀，高度≤3mm 57例，≤2mm 35例。矢状位呈新月形57例，呈弧线状35例。垂体柄居中80例，轻度左偏5例，轻度右偏7例，拉长直达鞍底92例。鞍底骨质轻度变薄下陷42例。视交叉受压上抬5例。冠状位垂体左右径〈10mm，上缘平直30例，凹陷62例。视交叉与垂体距离拉长，垂体柄居中，加上压向鞍底的垂体，呈“工”字形30例，呈“锚”形62例。结论MRI检查是发现空蝶鞍的有效方法。Objective To investigate the MR features of empty sella. Methods Ninty - two cases diagnosed as ernptu sella in our hospital was included,and their MR features was analysed retrospectively. Results Sella was spherical expand 45 cases. On the cerebrospinal fuild signal and with the saddle on the same pool, the pituitary thinning close to the end of saddle or saddle hack, signal uniformity and a high degree of ≤3 mm of 57 cases,≤2 mm of 35 cases. Fifty -seven cases were crescent on sagittal position,35 cases arc- shaped. Pituitary stalk the middle 80 cases, five cases of mild left side, right side seven cases of mild, the longer direct access to saddle at the end of 92 cases. On mild bone thinning settlement at the end of 42 cases. Supraehiasmatic pressured upon five cases. Coronal pituitary diameter of less than 10 ram,straight on the fate of 30 cases,62 cases of depression. Suprachiasmatic and pituitary longer distance, the pituitary stalk the center, coupled with pressure to the saddle at the end of the pituitary,were ＂tramline＂ shape of 30 cases,were ＂anchor＂ shape of 62 cases. Conclusions MR is the effective method in diagnosing empty sella.
