Intoduction Headache with or without neck pain can be the only manifestation of cervical arterial dissection. Headache is the most common and the most frequent onset symptom in cervical arterial dissection. Section 6.5.1 of the International Classification of Headache describes facial or neck pain imputable to arterial dissection. The described diagnostic criteria are: acute onset of facial or neck pain with or without other neurological signs or symptoms, developing in close temporal relationship and on the same side of the dissection and disappearing within 1 month. In addition, the dissection must be diagnosed by appropriate vascular/neuroimaging investigations. Post-traumatic and spontaneous dissection occurrence is described in the literature; these occurrences although rare should be considered and promptly investigated in order to begin an effective treatment.
