AbstractCervical pain caused by the elongation of the styloid process (Eagle syndrome) is well known to otolaryngologists but is rarely considered by vascular surgeons. We report two patients with cerebrovascular symptoms of Eagle syndrome treated in our medical center in the past year. Case 1: an 80-year-old man with acromegaly presented with dizziness and syncope with neck rotation. The patient was noted to have bilateral elongated styloid processes impinging on the internal carotid arteries. After staged resections of the styloid processes through cervical approaches, the symptoms resolved completely. Case 2: a 57-year-old man presented with acute-onset left-sided neck pain radiating to his head immediately after a vigorous neck massage. Hospital course was complicated by a 15-minute transient ischemic attack resulting in aphasia. Angiography revealed bilateral dissections of his internal carotid arteries, with a dissecting aneurysm on the right. Both injuries were immediately adjacent to the bilateral elongated styloid processes. Despite immediate anticoagulation therapy, he experienced aphasia and right hemiparesis associated with an occlusion of his left carotid artery. He underwent emergent catheter thrombectomy and carotid stent placement, with near-complete resolution of his symptoms. Elongated styloid processes characteristic of Eagle syndrome can result in both temporary impingement and permanent injury to the extracranial carotid arteries. Although rare, Eagle syndrome should be considered in the differential diagnosis in patients with cerebrovascular symptoms, especially those induced by positional change.Copyright © 2012 Annals of Vascular Surgery Inc.
