Cervical CT scans around the odontoid process (dens). a The axial image demonstrates the right, dominant, half-ringed form of calcification at the posterolateral side of the dens. b The coronal image demonstrates the remarkable crown-like calcifications around the dens. c The sagittal image demonstrates the linear calcification at the posterior side of the dens. d A 3D reconstruction obtained from data of a plain cervical CT demonstrates the marked crown-like calcification at the posterior side of the dens. The diagnosis of CDS was confirmed by these cervical CT findings.

On June 28, a cervical plain CT scan detected a remarkable crown-like calcification surrounding the odontoid process (fig. 1a-c). A three-dimensional (3D) reconstruction obtained from data of the cervical plain CT confirmed this remarkable crown-like calcification on the posterior side of the dens (fig. 1d).
