Abstract
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.
