Crowned dens syndrome (CDS) is characterized by acute severe neck pain, mobility restrictions of the neck, calcifications around the odontoid process of the axis on computed tomography and elevated inflammatory responses. We encountered a protracted CDS patient for whom corticosteroid administrations were effective. We report the clinical course and radiographic changes of the patient from follow-up radiographs. In radiographs of the cured patient, calcifications around the odontoid process on CT had reduced, and atlantoaxial joint-centered wide inflammatory changes on MRI had disappeared.
