Tumor metastasis to the hypophyseal system has rarely been reported with either clinical or radiographic evidence. A 52-year-old woman presented with polydipsia, polyuria, and loss of appetite. She was diagnosed as having diabetes insipidus caused by pituitary micrometatasis of lung adenocarcinoma. After she had been treated with radiation therapy to the pituitary gland, the gland size was reduced as confirmed by magnetic resonance imaging, and her urine volume decreased. However, meningitis carcinomatosa appeared later. This was a rare case of secondary diabetes insipidus due to pituitary metastasis of lung cancer.
肿瘤转移至垂体系统的临床或影像学证据鲜有报道。一名52岁女性出现烦渴、多尿和食欲减退症状。她被诊断为因肺腺癌垂体微转移导致的尿崩症。在接受垂体放疗后，磁共振成像证实垂体大小缩小，尿量减少。然而，随后出现了癌性脑膜炎。这是一例因肺癌垂体转移导致继发性尿崩症的罕见病例。
