我们描述了一个不寻常的情况下，垂直震荡和主要位置下拍眼球震颤与成人阿诺德-基亚里畸形。眼运动异常的一个独特方面是眼球震颤的间歇性，这与头部位置、情绪或Valsalva手法无关。常规计算机断层扫描显示后窝视野正常，但甲硝唑胺脑池造影显示髓外肿块，最初认为是脑膜瘤。有一个戏剧性的视力下降和下降的失稳后枕下颅骨切除术为阿诺德-基亚里畸形。眼球震颤特征通过连续定量眼动记录记录。
We describe an unusual case of vertical oscillopsia and primary position downbeat nystagmus associated with an adult Arnold-Chiari malformation. A unique aspect of the ocular motor abnormality was the intermittent nature of the nystagmus, which displayed no relationship to head position, emotion, or the Valsalva maneuver. Conventional computed tomography with posterior fossa views was normal, but metrizamide cisternography demonstrated an extramedullary mass originally believed to be a meningioma. There was a dramatic diminution of the visual comdaints and downbeat nvstamus after suboccipital craniectomy for an Arnold-Chiari malformation. Nystagmus characteristics were documented by serial quantitative eye movement recordings.
