    Abstract

    Patients with Crowned dens syndrome typically present with severe neck pain and have calcification around the axial odontoid process on radiographs.

    To our knowledge, Crowned dens syndrome is unreported in the Korean literature and the clinical features remain unclear.

    We present Crowned dens syndrome as a cause of acute cervical pain and review the literature.

(A) The axial view of computed tomography scans showed multiple calcifications (0.8×1.2×1.0 cm) in right lateral aspect of odontoid process of C2. (B) The coronal view of computed tomography scans showed calcifications (0.8×1.2×1.0 cm) in right lateral aspect of odontoid process of C2.
