We present a case of acute-onset diabetes insipidus in a 69-year-old man who had been treated for lung cancer. T1-weighted MR images showed a thickened pituitary stalk and absence of the normal high intensity of the posterior pituitary lobe. Dynamic imaging demonstrated poor enhancement in the posterior lobe, whereas the anterior lobe was strongly enhanced. Autopsy revealed that metastatic tumor from lung cancer had infiltrated the posterior lobe as well as the pituitary stalk.
我们报告一例69岁曾接受肺癌治疗的男性患者突发尿崩症的病例。T1加权磁共振成像显示垂体柄增粗，垂体后叶正常高信号消失。动态成像显示后叶强化不佳，而前叶强化明显。尸检发现肺癌转移瘤已浸润垂体后叶及垂体柄。
