Eagle syndrome: A case report of stylocarotid syndrome with internal carotid artery dissection

Interv Neuroradiol. 2017 Aug;23(4):433-436. doi: 10.1177/1591019917706050. Epub 2017 May 22.

Abstract

Eagle syndrome is defined by an elongated styloid process or a calcified stylohyoid ligament that impinges on surrounding structures and causes a variety of symptoms. Classically, Eagle syndrome presents as neck, throat, or ear pain. The vascular variant, stylocarotid syndrome, can present as headache, transient ischemic attack, or stroke. Carotid artery dissection is a rare complication of stylocarotid syndrome. We report a case of stylocarotid syndrome in a 60-year-old man who presented with a right internal carotid artery (ICA) dissection and focal neurological deficits. Computed tomography with three-dimensional reformatting was used in the evaluation of his pathology. His dissecting right ICA was stented with subsequent symptom resolution. Improved recognition of the relationship between an elongated styloid or calcified stylohyoid ligament and symptomatology may lead to optimal etiology recognition and directed treatment.

Keywords: Eagle syndrome; computed tomography (CT) with three-dimensional (3D) reformatting; elongated styloid process; internal carotid artery (ICA) dissection; stenting of right internal carotid artery (ICA); stroke; stylocarotid syndrome.
