Abstract

We report a case of Wegener granulomatosis causing hyperprolactinemia followed by central diabetes insipidus. The initial T1-weighted MR image showed an isointense heterogeneous sellar mass. After the onset of diabetes insipidus, repeat sagittal and postcontrast T1-weighted images showed marked infundibular thickening, enlargement of the sellar mass, and enhancement of both the infundibulum and hypothalamus. Follow-up MR after marked clinical response to corticosteroids showed nearly complete resolution of the aforementioned abnormalities.

摘要

我们报告一例韦格纳肉芽肿病导致高泌乳素血症,随后发展为中枢性尿崩症的病例。最初的T1加权磁共振成像显示鞍区有一个等信号的不均匀肿块。尿崩症发作后,重复矢状位和增强后T1加权图像显示漏斗部明显增厚、鞍区肿块增大以及漏斗部和下丘脑强化。对皮质类固醇有明显临床反应后的随访磁共振成像显示上述异常几乎完全消退。
