The authors report a symptomatic congenitally anomalous ectatic vertebral artery not passing through the transverse foramen of the atlas (C-1), but instead piercing the dura mater below the posterior arch of the C-1 in the atlantoaxial (C1-2) interlaminar space. This occurrence is exceptionally rare, but in this case it was uniquely associated with occipital neuralgia due to vascular compression of the C-2 root. Microvascular decompression was curative. Neuroradiological and surgical findings are presented and their implications discussed.
作者报告了一例有症状的先天性异常扩张椎动脉，该动脉未穿过第一颈椎（C-1）的横突孔，而是在寰枢椎（C1-2）层间间隙中穿过第一颈椎后弓下方的硬脑膜。这种情况极为罕见，但在该病例中，它与因C-2神经根血管受压导致的枕神经痛独特相关。微血管减压术治愈了该疾病。文中展示了神经放射学和手术结果，并讨论了它们的意义。
