Cerebral angiographic changes on serial examination of a patient with migraine

Curious cerebral angiographic changes are described in a 27-year-old female migraine patient. During the period of observation of this patient, both the intracranial carotid artery and the vertebrobasilar artery systems presented unusual and fascinating cerebral arteriographic pictures. In an attack of migraine, angiography showed that all the intracranial secondary and tertiary branches of the carotid arterial system were dilated without showing any changes in the extracranial arteries and when the migraine attack had subsided, all branches of the carotid arteries as well as the vertebrobasilar arteries demonstrated abnormal segmental narrowings or vasospasm. These sequential angiographic changes have not been hitherto reported in migraine.
