Radiographic Findings

X-Ray of the cervical spine (Film 1) reveals amorphous calcification anterior to the C1 and C2 vertebrae (yellow arrow) with marked prevertebral soft tissue swelling (red arrow). This is seen with higher magnification in Film 2. There is no evidence of fracture. A confirmatory CT scan (not shown) often reveals calcification of the longus colli tendon at its insertion site.
