Aberrant articulation between two anterior tubercles is a rare congenital anomaly that should be considered for patients showing a bony projection anterior to the vertebral body on a lateral radiograph of the cervical spine. We present a case of an elongation of the anterior tubercles of the transverse processes of both the fifth and sixth cervical vertebrae. This finding is probably a form of supernumerary cervical rib developing at a level above the lowest cervical spine.
