Vascular compression of medulla or spinal cord at the cervico-medullary junction has been commonly described in the literature and is often attributed to dolichoectasia of the vertebrobasilar arteries. We describe a case of anomalous course of the cervical segments of the bilateral vertebral arteries which were seen entering the spinal canal directly after exiting the transverse foramen of axis and causing significant cord compression at the cervico-medullary region leading to spastic quadriparesis.
延髓或脊髓在颈髓交界处的血管受压在文献中已有普遍描述,通常归因于椎基底动脉的迂曲扩张。我们描述了一例双侧椎动脉颈段走行异常的病例,这些椎动脉在离开枢椎横突孔后直接进入椎管,在颈髓区域造成明显的脊髓压迫,导致痉挛性四肢瘫。
