[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.
