摘　　要：目的 通过垂体MRI观察中枢性尿崩症患者垂体后叶及垂体柄的改变。资料与方法 回顾性分析37例经临床和实验室证实的尿崩症患者的MRI资料,分析其临床与MRI表现。结果 37例中导致中枢性尿崩症的病因包括感染、肿瘤性病变、创伤及空蝶鞍。按其MRI表现分为3种类型:垂体柄病变;单纯垂体后叶高信号消失;空蝶鞍。结论 对于尿崩症的患者,结合临床表现,利用垂体MRI检查,可显示垂体后叶及垂体柄的改变,为临床论断、治疗提供可靠依据。Objective To investigate MRI manifestations of the posterior lobe and stalk of the hypophysis in central diabetes insipidus. Materials and Methods MRI findings and clinical data in 37 patients with clinically- and laboratorially-proved central diabetes insipidus were retrospectively analyzed. Results The etiology causing central diabetes insipidus in this study included infection, tumor, trauma and empty-sella syndrome. On MRI, the disease showed three patterns: (1) thickened pituitary stalk (71%); (2) absence of high signal normally seen in posterior lobe on T1WI (57%) ; (3) Empty-sella sign. Conclusion For patients with central diabetes insipidus, MRI can demonstrate the morphological and signal changes of the posterior lobe and the stalk of the hypophysis. Combined with the clinical data, MRI can provide useful information for the diagnosis and management.
