This article presents the case of a healthy 46-year-old man who experienced
a dissection of the internal carotid artery. The diagnosis of this condition
is not usually clear-cut, especially in a young patient with unremarkable
medical history, and because of the similarity of symptoms with migraine.
Often there is no obvious cause of a cerebral artery dissection, although
subtle abnormalities of connective tissue may be present. Anticoagulation
is generally used for therapy, but clinical trials are lacking. Carotid artery
dissection should be considered as a cause of stroke in young healthy adults.
