ResumoFull type: it forms a complete bony ring.Incomplete type: some portions of the bony ring are defective.Calcified type: there is a linear or amorphous calcification.In lateral cervical spine radiography, we can observe a bony ring (Fig. 1).The presentation of these bony arches or bony bridges can be unilateral or bilateral (Cho).While the observation of this calcification is not a diagnosis issue, determining their location (unilateral or bilateral) and identifying the affected side of C1 is very difficult with lateral and anteroposterior radiographic views.
