A 34-year-old woman was admitted to our hospital because of sudden left hemiparesis and amaurosis fugax in the right eye. She had no headache, neck pain or trauma. Diffusion-weighted MRI demonstrated acute cerebral infarctions in the right middle cerebral artery territory, and in the border zone between the territories of the right anterior and middle cerebral arteries. T1-weighted MRI demonstrated an intramural hematoma in the right internal carotid artery. Carotid ultrasonography performed on the 4th hospital day showed severe stenosis (ECST 77%, area 89%) in the right internal carotid artery. Cerebral angiography performed on the 20th hospital day revealed an irregular, long-distance stenosis (string sign) in the cervical portion of the right internal carotid artery. Follow-up ultrasound examination showed recanalization of the right internal carotid artery. Therefore, the patient was diagnosed as having internal carotid artery dissection. We emphasize the usefulness of a noninvasive technique such as cervical ultrasound examination with color-coded Doppler for the diagnosis and follow-up of nontraumatic extracranial internal carotid artery dissection.
