Radiograph and CT of secondary accessory ossification center of vertebral body mimicking cervical spine fracture
Lateral radiograph of the cervical spine (left) shows a small ossific fragment anterior and superior to the C6 vertebral body. There is no prevertebral swelling and the alignment of the cervical spine is normal. Sagittal CT without contrast of the cervical spine (right) shows that the ossific fragment is well corticated.

The diagnosis was a secondary ossification center of the cervical spine mimicking a cervical spine fracture.
