The sagittal MRI of the cervical spine shows prevertebral bone formation and soft tissue ossification, forming a bridge of bone connecting the anterior parts of the cervical vertebrae from C3 downward until T1 vertebra. The disc spaces are more or less preserved.
The axial MRI images show that the bone formation is anterior and anterolateral to the vertebral bodies.
There are also degenerative changes of the atlantoaxial joint.
