See-saw nystagmus has been seen with tumors of the parasellar region and diencephalon, brain-stem vascular lesions, syringobulbia, and after trauma. We report see-saw nystagmus in an adult with a Chiari malformation that was diagnosed by magnetic resonance imaging and confirmed intraoperatively. This patient's condition improved after surgical decompression. An association between see-saw nystagmus and Chiari malformation is potentially important because early diagnosis and decompression may improve neurologic function and prevent further deterioration.
跷跷板样眼球震颤可见于鞍旁区域和间脑肿瘤、脑干血管病变、延髓空洞症以及外伤后。我们报告了一例成人患者出现跷跷板样眼球震颤，该患者通过磁共振成像诊断为Chiari畸形，并在术中得到证实。该患者在手术减压后病情改善。跷跷板样眼球震颤与Chiari畸形之间的关联可能具有重要意义，因为早期诊断和减压可能改善神经功能并防止进一步恶化。
