Radicular pain in the left upper extremity. Sagittal alignment is notable for straightening. In addition, there is 3 mm anterior subluxation of C3 on C4. The vertebral bodies are preserved in height. Marrow signal is notable for mild type I degenerative change subjacent to an intrabody herniation through the superior endplate of C5 and the right C3-C4 facet, which also shows a subchondral cyst. There is desiccation of all cervical discs. There is moderate height loss at C5-C6 and C6-C7. Spinal canal narrowing is mild at C3-C4, C5-C6 and C6-C7 levels as described below. There is no cervical spinal cord signal abnormality. Included posterior fossa structures are grossly unremarkable.C2-C3: Very shallow ventral indentation of the thecal sac by disc-osteophyte complex but no significant spinal canal stenosis. Uncovertebral and right more than left facet arthropathy result in mild right foraminal stenosis.C3-C4: Disc-osteophyte complex and ligamentum flavum thickening in addition to mild bilateral uncovertebral and severe right and moderate left facet arthropathy result in mild spinal canal stenosis and moderate bilateral foraminal stenoses.C4-C5: Left more than right uncovertebral and facet arthropathy result in moderate bilateral foraminal stenoses but no significant spinal canal stenosis.C5-C6: Disc-osteophyte complex in addition to bilateral uncovertebral and facet arthropathy are associated with mild spinal canal stenosis and moderate bilateral neural foraminal stenoses.C6-C7: Disc-osteophyte complex in addition to bilateral uncovertebral and facet arthropathy are associated with mild spinal canal stenosis and moderate bilateral neural foraminal stenoses.C7-T1: Eccentric to the left disc-osteophyte complex is present but no significant spinal canal or neural foraminal stenosis.
Multilevel degenerative cervical spondylosis associated with mild C3-C4, C5-C6 and C6-C7 spinal canal stenoses but no spinal cord signal abnormality. There is also moderate bilateral neural foraminal stenoses at C3-C4 through C6-C7.
