A 10-year-old boy had a 4-month history of blurred vision and severe occipital headaches. Visual acuity was diminished bilaterally, but ophthalmoscopy was normal, and the correct diagnosis was delayed until inferior bitemporal defects were found. Cranial CT scans and vertebral angiograms demonstrated a giant aneurysm at the bifurcation of the basilar artery. Bitemporal hemianopsia occurring in children is usually due to craniopharyngioma or chiasmal glioma. To the best of our knowledge, this is the first report of a patient whose chiasmal syndrome was due to a basilar artery aneurysm and whose visual deficit improved after occlusion of the aneurysm.
一名10岁男孩有4个月视力模糊和严重枕部头痛的病史。双侧视力下降，但眼底镜检查正常，正确诊断延迟至发现双颞下缺损。头颅CT扫描和椎动脉血管造影显示基底动脉分叉处有一个巨大动脉瘤。儿童出现双颞侧偏盲通常是由于颅咽管瘤或视交叉神经胶质瘤。据我们所知，这是第一例因基底动脉动脉瘤导致视交叉综合征且动脉瘤闭塞后视力缺陷改善的患者报告。
