Abstract

We report a case of radiation-induced optic neuropathy in a 32-year-old man with Cushing's disease and a recurrent tumour of the left cavernous sinus. The patient experienced rapid, painless loss of vision 4 years after treatment without recurrence of tumour or other visual disorder. MRI showed enlargement and contrast enhancement of the optic chiasm. A year later the patient was almost blind and MRI showed atrophy and persistent contrast enhancement of the chiasm.

摘要

我们报告一例32岁患有库欣病且左侧海绵窦肿瘤复发的男性患者发生放射性视神经病变的病例。该患者在治疗后4年出现快速、无痛性视力丧失，此时肿瘤无复发且无其他视觉障碍。磁共振成像（MRI）显示视交叉增大且有对比增强。一年后，患者几乎失明，MRI显示视交叉萎缩且持续有对比增强。
