Straightening of the cervical spine is seen indicating severe muscle spasm.
Vertebral bodies' heights and disk spaces are preserved.
C5-C6: Left posterior lateral disk protrusion is seen indenting thecal sac anteriorly and causing narrowing of the left nerve root exit canal without compressing the spinal cord.
C6-C7: Large left posterior lateral disk protrusion is seen compressing the left anterior lateral aspect of the spinal cord and compressing the left nerve root at its exit canal significantly.
The rest of the cervical intervertebral disks appears normal without evidence of focal disk protrusion or extrusion.
NB:
There is a lobulated soft tissue mass lesion arising from the right posterior inferior aspect of the clivus measuring about 3.2 cm extending posteriorly into the posterior cranial fossa compressing the medulla oblongata and the cervical medullary junction posteriorly without infiltrating it.
The findings are consistent most likely with chordoma.
