A 70-year-old male presented with pituitary metastasis from transitional cell carcinoma of the urinary bladder manifesting as sudden headache, transient unconsciousness, and visual disturbance mimicking apoplexy of pituitary adenoma. Computed tomography showed a suprasellar tumor with intratumoral and intraventricular hemorrhage. Magnetic resonance imaging demonstrated an intra- and suprasellar mass lesion mimicking pituitary adenoma. Diabetes insipidus developed soon after. The tumor was subtotally removed. Histological examination revealed transitional cell carcinoma. An intratumoral hemorrhage may be associated with a pituitary metastasis if the patient presents with symptoms such as pituitary apoplexy.
一名70岁男性因膀胱移行细胞癌垂体转移就诊，表现为突发头痛、短暂意识丧失及视觉障碍，酷似垂体腺瘤卒中。计算机断层扫描显示鞍上肿瘤伴瘤内及脑室内出血。磁共振成像显示鞍内及鞍上肿块病变，酷似垂体腺瘤。术后不久出现尿崩症。肿瘤次全切除。组织学检查显示为移行细胞癌。如果患者出现垂体卒中样症状，瘤内出血可能与垂体转移有关。
