This 70-year-old woman presented with a left C2 solitary metastatic lesion producing ipsilateral occipital pain associated with contralateral fronto-orbital dysaesthesias. Examination revealed analgesia in the left C2 dermatome and hyperaesthesia in the right forehead. These symptoms and findings resolved following a course of radiation therapy to the C2 metastasis. Ipsilateral trigeminal dysaesthesias produced by cervical lesions have been described, however, contralateral cervicogenic trigeminal dysaesthesias have not. Relevant experimental data are analysed; neural pathways are suggested by which a cervical lesion, especially at C2 or C3, may produce trigeminal dysaesthesias referred ipsilaterally or contralaterally.
这位70岁女性患者出现左侧C2孤立性转移病灶，伴有同侧枕部疼痛，并伴有对侧额眶感觉异常。检查发现左侧C2皮节感觉缺失，右侧前额感觉过敏。对C2转移灶进行一个疗程的放射治疗后，这些症状和体征消失。虽然已经有关于颈部病变导致同侧三叉神经感觉异常的描述，但对侧颈源性三叉神经感觉异常尚未见报道。本文分析了相关实验数据；提出了神经通路，通过该通路，颈部病变，尤其是C2或C3水平的病变，可能会导致同侧或对侧的三叉神经感觉异常。
