Hemicrania continua in carotid artery dissection - symptomatic cases or linked pathophysiology?

Background Hemicrania continua (HC) -like headaches have been rarely reported as symptomatic headaches, including cases secondary to cervical artery dissection. Case series We present five cases of HC-like headaches following cervical artery dissection, in three cases with specific indomethacin response. In two cases, comorbidity of fibromuscular dysplasia (FMD) was noted. Conclusion Carotid artery dissection may result in an HC-like headache syndrome. A specific response to indomethacin does not rule out dissection as underlying pathology. Screening for extracranial manifestations of FMD should be considered, especially in middle-aged females.
