We report a case of cerebral hemorrhagic infarction after radiation for pituitary adenoma. A 55-year-old woman was hospitalized to check for aldosteronism, post-operative pituitary function, and recurrence of thyroid cancer. She had short-term memory disturbance beginning two months prior to admission. Brain MRI showed a T1 and T2 high intensity lesion of her left anterolateral thalamus. Brain MRA revealed a narrowing in her left middle cerebral artery. The abnormal brain lesion was diagnosed as cerebral hemorrhagic infarction. She had received radiation therapy for pituitary adenoma 20 years earlier. It was considered that her cerebral hemorrhagic infarction was caused by radiation therapy.
我们报告一例垂体腺瘤放疗后发生脑出血性梗死的病例。一名55岁女性因检查醛固酮增多症、垂体术后功能及甲状腺癌复发而入院。她在入院前两个月开始出现短期记忆障碍。脑部MRI显示左侧丘脑前外侧T1及T2高信号病变。脑部MRA显示左侧大脑中动脉狭窄。异常脑病变被诊断为脑出血性梗死。她20年前曾接受过垂体腺瘤放疗。考虑其脑出血性梗死是由放疗所致。
