我们描述了一个罕见的上颈椎硬膜外神经鞘瘤压迫主导颈内静脉（IJV）的病例，表现为非典型头痛。一名 50 岁的女性主诉颈部皮下肿块，并伴有非典型头痛。放射学检查显示，右侧 IJV 前方被 C2 硬膜外肿块压迫，并且通过颈深静脉的侧支脑静脉引流明显扩张而闭塞。通过后外侧入路进行次全切除，非典型头痛立即消失。本病例表明上颈椎硬膜外神经鞘瘤可压迫IJV并表现为脑静脉循环障碍。
We describe a rare case of extradural schwannoma in the upper cervical spine compressing the dominant internal jugular vein (IJV) presenting with atypical headaches. A 50-year-old woman complained of a subcutaneous neck mass associated with atypical headaches. Radiological examinations revealed the right IJV was compressed anteriorly by C2 extradural mass and occluded with markedly dilated collateral cerebral venous drainage through deep cervical veins. Subtotal removal was performed via the posterolateral approach and the atypical headaches resolved immediately. This case demonstrates that extradural schwannoma in the upper cervical spine could compress the IJV and manifest as cerebral venous circulation disturbances.
