Cervico-occipital junction infectious osteoarthritis complicated with atlantoaxial dislocation, cervical abscesses and epiduritis: A case report and review of the literature

Abstract

Craniocervical junction infections are considered a rare condition and can be associated with degradation of the odontoid ligaments and, the risk of a subsequent atlantoaxial subluxation or dislocation. Osteomyelitis at this level is often seen in immunocompromised patients with, intravenous drug use or infective endocarditis. Atlantoaxial subluxation associated with pharyngeal infection or its surrounding tissues is called Grisel's syndrome. We report the case of a 29-year-old man diagnosed with infectious cervico-occipital osteoarthritis complicated by atlantoaxial dislocation, abscesses located in the retropharyngeal space, and the prevertebral space as well as upper cervical epiduritis. Our purpose is to highlight the role of radiologists in diagnosing this rare yet deadly condition.
