Numbness in thumb radiating to shoulder, atrophy of thenar eminence There is cerebellar tonsillar ectopia. Craniovertebral junction appears otherwise within normal limits. The cervical vertebral bodies are appropriate in height. Alignment is grossly maintained aside from mild reversal of cervical lordosis. Bone marrow signal is benign. No abnormal enhancement is seen in the cervical cord, spine, or paraspinous soft tissues. Examination is slightly motion degraded; however, no cord signal abnormality is definitively appreciated.There appears to be mild congenital narrowing of the cervical spinal canal with superimposed degenerative changes; individual levels as described below:C2-3: No significant compromise to the spinal canal or neural foramina.C3-4: Small disc osteophyte complex with mild to moderate spinal canal stenosis. There is bilateral uncovertebral hypertrophy with moderate to severe bilateral neural foraminal stenosis.C4-5: Small disc osteophyte complex, ligamentum flavum thickening, and bilateral uncovertebral hypertrophy. There is mild impression on the right ventral cord with overall mild to moderate degree of spinal canal stenosis. Uncovertebral hypertrophy results in moderate to severe bilateral neural foraminal stenosis.C5-6: Small disc osteophyte complex, ligamentum flavum thickening, and bilateral uncovertebral hypertrophy. There is mild impression on the cord with mild to moderate degree of spinal canal stenosis. Uncovertebral hypertrophy results in moderate to severe bilateral neural foraminal stenosis, C6-7: Small disc osteophyte complex, ligamentum flavum thickening, and bilateral uncovertebral hypertrophy. There is mild spinal canal stenosis. There is moderate left and mild right neural foraminal stenosis.C7-T1: No significant compromise to the spinal canal or neural foramina.Paraspinous soft tissue structures appear within normal limits.
Multilevel degenerative changes in the cervical spine with mild to moderate degree of spinal canal stenosis at C3-C4, C4-C5, C5-C6, and to a slightly lesser degree at C6-C7. There is significant neural foraminal stenosis at these levels bilaterally as detailed above which may be impinging on the exiting nerve roots.
