Abstract:
Summary A patient with migraine headaches of the ldquoclusterrdquo variant type is presented in whom vasospasm of the middle cerebral artery, the anterior cerebral artery and the internal carotid artery triggered a pain episode identical in character and severity to the headaches which had led to her investigation. Vasospasm associated with the painful phase of headache in this case conflicts with the more accepted theory that the pain phase of a vascular headache is related to vasodilatation of cerebral or extracerebral vessels. The literature is reviewed.
Keywords:Vascular spasm  Carotid artery  Vascular headache
