摘要
目的 :观察中枢性尿崩症患者鞍区磁共振成像 (MRI)的影像变化。方法 :对 12例非尿崩症对照者及 48例临床诊断的中枢性尿崩症 (CDI)患者同时进行鞍区MRI扫描。结果 :12例对照组垂体后叶均见高信号存在 ,垂体柄正常 ;48例CDI中 44例垂体后叶高信号消失 ,18例伴垂体柄增粗 ;48例中仅 10例证实鞍区存在器质性病变。结论 :MRI垂体后叶高信号消失 ,是CDI患者特征性表现 ,部分伴垂体柄增粗 ,对CDI的病因诊断和指导治疗具有很大价值。
Objective To observe the changes of magnetic resonance imaging(MRI) of sellar area in patients with cnetral diabetes insipidus(CDI) Methods Sellar were examined with MRI in 12 subjects without diabetes insipidus and 48 patients with CDI Results The hyperintensesignal(HIS) of posterior pituitary was present in all 12 subjects without diabetes insipidus,pituitary stalk all was normal;the normal HIS of postterior pituitary was absent in 44/48 patients with CDI,enlargment of pituitary stalk finded in 18/48 patients with CDI,organic diseases in sellar area were demonstrated in 10/48 patients Conclusion The disappearance of posterior pituitary HIS is a characterization of MRI in patients with CDI,partial patients also have enlargment of pituitary stalk,MRI is helpful for the aetiological diagnosis and treatment of the CDI
