A rare case of radicular pain in the arm due to compression of the C6 nerve root by coiling of the vertebral artery is reported; the diagnosis was confirmed by computed tomography (CT), magnetic resonance (MR) angiography and echocolordoppler. Although the enlargement of an intervertebral foramen by a tortuous vertebral artery has been described previously, the occurrence of radicular pain is exceptional. Magnetic resonance imaging (MRI), MR angiography and echocolordoppler allow to differentiate foraminal enlargement due to vascular anomalies of the vertebral artery from that more commonly due to tumor compression, mainly from neurinoma. Surgical decompression may be considered in symptomatic cases.
报告了一例罕见的因椎动脉盘绕压迫C6神经根导致手臂放射性疼痛的病例；诊断通过计算机断层扫描（CT）、磁共振（MR）血管造影和超声彩色多普勒得以证实。尽管先前已描述过椎动脉迂曲导致椎间孔扩大，但放射性疼痛的发生却很罕见。磁共振成像（MRI）、MR血管造影和超声彩色多普勒有助于将因椎动脉血管异常导致的椎间孔扩大与更常见的因肿瘤压迫（主要是神经鞘瘤）导致的椎间孔扩大区分开来。有症状的病例可考虑手术减压。
