We report a patient who presented with a painful pupil-involving third- nerve palsy.Cerebral angiography revealed a high-grade stenosis of the ipsilateral internal carotid artery with a 4-cm intraluminal thrombus. Following emergent carotid endarterectomy,the patient's partial third- nerve palsy resolved in 1 hour.A pupil-involving third-nerve palsy may be an unusual presentation of impending carotid occlusion. |
