[Unilateral atypical neck pain in Eagle syndrome].

This article is an introduction to Eagle syndrome as a differential diagnosis in patients with lateral neck pain, a symptom, which is often difficult to diagnose and where the accepted treatment covers a variety of forms. This was the case for a 51 year-old man with lateral neck pain and a crunchy sensation/sound when he turned his head. After years of pain, the right examination and a computed tomography finally suggested Eagle syndrome. The patient had severe symptoms and was treated with an operation by which part of the ossificated stylohyoid ligament was removed. The operation relieved him of all his symptoms.
