Diagnosis: Spinal stenosis, cervical regionClinical question: right arm pain and weaknessSigns and Symptoms: right arm pain and weakness The cervical vertebral bodies are appropriate in overall alignment and height. The cervical spinal cord has normal signal characteristics and overall morphology. The patient is status post anterior fusion and disc spacer placement at the C5-6-7.Axial imaging is degraded by phase encoding artifact and motion artifact. There is mild reversal of normal cervical curvature which was also present on the prior exam but not substantially changed. Please note that the reversal of normal cervical curvature may be positional effect rather than true reversal. This is centered at approximately C5-6. Compared to the previous exam there is no observable significant interval change.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.At C4-5 there is no significant compromise to the spinal canal or neural foramina.At C5-6 there is no significant compromise to the spinal canal or neural foramina. There is mild narrowing of the neural foramina bilaterally at this level which is unchanged since the prior exam.At C6-7 there is no significant compromise to the spinal canal. There is left sided uncovertebral osteophyte formation present associated with narrowing of the neural foramen. Some degree this was also present on the prior exam.At C7-T1 there is no significant compromise to the spinal canal or neural foramina.The vertebral artery flow voids appear to be intact.
1.The patient is status post anterior cervical fusion from C5 through C7. There is redemonstration and no change in encroachment of the left-sided exiting nerve roots at C6-7 as a result of degenerative change. Apparent mild reversal of the normal cervical curvature would be better assessed on upright plane film exams.2.Exam is degraded by artifact including phase encoding artifact and some mild motion by the patient.
