Abstract
A case is reported of a patient with nocturnal myoclonus and weakness of the left arm in whom a round defect was seen in the arch of C2 on the left side. Vertebral angiogram revealed that this was caused by an anomalous course of the vertebral artery and not by an aneurysm. A similar location of this foramen was found in nine of 100 cases reviewed.
摘要
报告了一例患有夜间肌阵挛和左臂无力的患者，其左侧C2椎弓处可见一个圆形缺损。椎动脉血管造影显示，这是由椎动脉走行异常引起的，而非动脉瘤所致。在回顾的100例病例中，有9例发现了类似的孔位置。
