Case 1. Unenhanced cervical spinal CT images of a 74-year-old woman with CDS (window level: 500 HU; window width: 2,000 HU). Axial (A1, A2) CT images show lined-calcifications around the dense area (arrows), the mean CT number 183–342 HU (ROI area: 1.0 mm2) (A1). Sagittal (B) and coronal (C) MPR imaging (500 HU; 2,000 HU) shows lined-calcifications at the posterior and superior aspects of the dens (arrows). CT, computed tomography; CDS, crowned dens syndrome; ROI, region of interest; MPR, multi-planar reformatting.

Case 2. The other patient with CDS, a 65-year-old man, in whom all CT findings resemble those of case 1. Axial (A1, A2) CT image unenhanced neck CT images (window level: 500 HU; window width: 2,000 HU) show lined-calcifications around the dense (A2 arrows), the mean CT number 182–257 HU (A1). Sagittal (B) MPR imaging (500 HU; 2,000 HU) shows lined-calcifications at the posterior and superior aspects of the dens (arrows). CT, computed tomography; CDS, crowned dens syndrome; MPR, multi-planar reformatting.
