CASE REPORT
A 20-year-old female presented with horizontal jerk nystagmus, blurred vision, severe headaches, unsteady gait, and paresthesia. Magnetic resonance imaging revealed Chiari malformation I. Symptoms resolved after decompression of the posterior cranial fossa and removal of the right cerebellar tonsil.
COMMENTS
Conditions associated with acquired periodic alternating nystagmus and ocular disorders associated with Chiari malformation are discussed. To our knowledge, this case is the first to report the resolution of periodic alternating nystagmus after neurosurgical decompression.
病例报告
一名20岁女性出现水平性眼球震颤、视力模糊、严重头痛、步态不稳和感觉异常。磁共振成像显示为Ⅰ型Chiari畸形。后颅窝减压及右侧小脑扁桃体切除术后症状缓解。
评论
讨论了与后天性周期性交替性眼球震颤相关的疾病以及与Chiari畸形相关的眼部疾病。据我们所知，该病例是首例报道神经外科减压术后周期性交替性眼球震颤缓解的病例。
