history of Chiari decompression in 1995Signs and Symptoms: neck and arm pain paresthesia The cervical vertebral bodies are appropriate in overall alignment and height. The cervical spinal cord has normal signal characteristics and overall morphology. There is multilevel disc desiccation present.The patient status post suboccipital craniectomy for Chiari 1 decompression.At C2-3 there is no significant compromise to the spinal canal or neural foramina.At C3-4 there is no significant compromise to the spinal canal. There is loss of disc space height as well as a mild disc bulge and mild uncovertebral osteophytes bilaterally. There is mild narrowing of neural foramina at this level.At C4-5 there is no significant compromise to the spinal canal. There is loss of disc space height, disc bulge and endplate and uncovertebral osteophytes is also mild posterior ligamentous hypertrophy at this level. There is a encroachment of the left-sided exiting nerve roots more than the right exiting nerve roots related to combination of disc material and osteophytes.At C5-6 there is no significant compromise to the spinal canal. There is loss of disc space height, disc desiccation and a disc bulge at this level. There is narrowing of the neural foramina bilaterally at this level with mild encroachment of exiting nerve roots.At C6-7 there is no significant compromise to the spinal canal. There is loss of disc space height, disc desiccation and a disc bulge at this level. There is narrowing of the neural foramina bilaterally at this level with mild encroachment of exiting nerve roots.At C7-T1 there is no significant compromise to the spinal canal or neural foramina.The vertebral artery flow voids appear to be intact.Incidental note is made of partial empty sella.
There are multilevel degenerative changes present in the cervical spine with associated narrowing of the neural foramina at multiple levels and some mild encroachment of exiting nerve roots at multiple levels as described above.
