49-year-old woman with history of left arm numbness and weakness. Craniovertebral junction appears within normal limits. The cervical vertebral bodies are appropriate in height. There is grade 1 retrolisthesis of C5 on C6 and C6 on C7, otherwise alignment is normal. Bone marrow signal is within normal limits. The cervical spinal cord has normal signal characteristics and overall morphology.Degenerative changes are seen in the cervical spine as described below:C2-3: No significant compromise to the spinal canal or neural foramina.C3-4: No significant compromise the spinal canal or neural foramina.C4-5: There is a disc osteophyte complex with effacement of the anterior thecal sac but no significant spinal canal or neural foraminal stenosis.C5-6: There is a disc osteophyte complex and uncinate hypertrophy, left greater than right. This results in moderate to severe left neural foraminal stenosis and mild to moderate right neural foraminal stenosis. There is minimal spinal canal stenosis.C6-7: There is a disc osteophyte complex and uncinate hypertrophy, left greater than right. This results in severe left neural foraminal stenosis and moderate right neural foraminal stenosis. There is mild central canal stenosis.C7-T1: No significant compromise to the spinal canal or neural foramina.The vertebral artery flow voids appear to be intact. Paraspinous soft tissue structures appear within normal limits.
Degenerative disc disease and retrolisthesis, worst from C5 to C7 with significant neural foraminal narrowing, left greater than right. No severe spinal canal stenosis.
