Reason: followup on extent of cervical stenosis and prior described vertebral disk bulge History: LEFT UE intermittent muscle weakness, spasms, tingling, especially when lying flat The cervical vertebral bodies are appropriate in overall alignment and height. The cervical spinal cord has normal signal characteristics and overall morphology.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 or neural foramina. There is a small central disk protrusion at this levelAt C4-5 there is no significant compromise to the spinal canal or neural foramina. There is right-sided facet hypertrophy at this level associated with a disk bulge and some mild narrowing of the right neural foramen. This facet hypertrophy appears to have not changed substantially when compared to the prior exam.At C5-6 there is no significant compromise to the spinal canal. There are bilateral uncovertebral osteophytes present at this level associated with narrowing of the neural foramina bilaterally and encroachment of the exiting nerve roots left worse than right. This was also present on the prior exam.At C6-7 there is no significant compromise to the spinal canal. There are bilateral uncovertebral osteophytes present at this level associated with narrowing of the neural foramina bilaterally and encroachment of the exiting nerve roots. This was also present on the prior exam. There are some endplate reactive changes present at this level which have mildly progressed since the prior examAt C7-T1 there is no significant compromise to the spinal canal or neural foramina. There is a left-sided perineural cyst present at T1-2.The vertebral artery flow voids appear to be intact.
1.Degenerative changes are present in the cervical spine which have not substantially changed when compared to the previous exam. There is neural foramen encroachment of exiting nerve roots at C4-5 on the right, C5-6 on the left and bilateral at C6-7. There are some endplate reactive changes present at C6-7 which have mildly progressed since the prior exam.
