Abstract

Most documented cases of radiation-induced optic neuropathy are unilateral and occur more than 1 year after radiotherapy to the sellar region. We describe a patient with bilateral radiation optic neuropathy 3 months following the completion of radiotherapy. MRI 13 months after the onset of visual failure showed bilateral optic atrophy with residual gadolinium enhancement.

摘要

大多数有记录的放射性视神经病变病例为单侧，且发生在蝶鞍区放疗后1年以上。我们报告1例在放疗结束3个月后发生双侧放射性视神经病变的患者。视力减退13个月后的MRI显示双侧视神经萎缩，钆剂增强持续存在。
