空蝶鞍综合征20例的临床和MRI分析

CLINICAL ANALYSIS AND MRI DIAGNOSIS OF TWENTY CASES WITH EMPTY SELLA SYNDROME

分析２０例空蝶鞍综合征（ＥＳＳ）的ＭＲＩ表现和其中１６例的内分泌改变。结果１６例ＥＳＳ均有内分泌功能异常。ＭＲＩ表现有蝶鞍充满长Ｔ＿１和长Ｔ＿２的脑脊液；垂体受压至鞍底，冠状位呈“锚”状，矢状位呈“新月”状；垂体柄延长。结果表明ＥＳＳ常具有内分泌功能紊乱，ＭＲＩ对ＥＳＳ具有特征性诊断意义。

his study analyzed 20 cases of empty sella syndrome(ESS)diagnosed by magnetic reso-nance imaging(MRI).Sixteen patients examined for endocrine function were all accompanied bydiHerent endocrine disturbances.The MRI characteristics of ESS were that CSF filled in thesella,the pituitary gland was flattened to the bottom and the pituitary shank stretched down-ward,the pituitary gland looked like an 'anchor' in the coronal section. The results showed thatESS could be characteristically diagnosed by MRI. The etiology and pathogenic mechanism ofESS was also discussed. Vascular defect and autoimmunity of pituitary gland may play an impor-tant etiological role in ESS.
