Two cases of progressive, occipital lancinating pain and dysesthesias associated with a sensory deficit of the C2 dermatome are presented. Symptoms were relieved, and C2 sensory function restored by releasing a hypertrophied atlanto-epistrophic ligament entrapping the C2 root and ganglion. The normal anatomy and abnormal surgical findings are described. C2 entrapment by the atlanto-epistrophic ligament is discussed in reference to other C2 lesions causing occipital pain. We conclude that some patients whose progressive occipital pain is accompanied by a C2 sensory deficit are suffering from entrapment of the C2 root and ganglion amenable to surgical decompression.
本文报告了两例伴有C2皮节感觉缺失的进行性枕部刺痛和感觉异常的病例。通过松解压迫C2神经根和神经节的肥大寰椎后弓韧带，症状得到缓解，C2感觉功能得以恢复。文中描述了正常解剖结构和异常手术发现。结合其他导致枕部疼痛的C2病变，讨论了寰椎后弓韧带对C2的卡压。我们得出结论，一些进行性枕部疼痛伴有C2感觉缺失的患者，患有C2神经根和神经节卡压，可通过手术减压治疗。
