[Progress on diagnosis and treatment of crown dens syndrome]

Abstract

Crowned dens syndrome(CDS) is a major imaging manifestation of "coronary" calcified deposits around the odontoid, with pain, stiffness, fever, and even cervical cord compression in the upper head and neck. It was first described by Bouvet et al. in 1985, and the onset was generally thought to be caused by crystal deposition. The clinical manifestations of CDS are often similar to meningitis and often accompanied by an increase in inflammatory markers in the blood. As a result, it is very easy to obtain missed diagnosis and misdiagnosis, and it is clinically prone to obtain wrong or unnecessary treatment. At present, the diagnosis of CDS is based on the imaging findings in CT as a "golden standard". NASIDs drugs and corticosteroids are the main treatment. The prognosis is also generally good, and the imaging findings of the patients with the disease disappear completely within 3 months.
