Right upper extremity paresthesia and pain. Cervical Spine: Craniovertebral junction appears within normal limits. The cervical vertebral bodies are appropriate height. There is straightening of the cervical spine curvature with minimal anterolisthesis of C4 on C5. 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 to the spinal canal or neural foramina.C4-5: Mild disk bulge. No significant compromise to the spinal canal or neural foramina.C5-6: There is left paracentral disk extrusion with effacement of the left ventral thecal sac and minimal impression on the left ventral cord. Dorsal thecal sac is patent. No significant compromise to the neural foramina.C6-7: No significant compromise to the spinal canal or neural foramina.C7-T1: There is moderate narrowing of the right neural foramen related to combination of uncovertebral hypertrophy and disk material. There is mild narrowing of the left neural foramina. No significant spinal canal stenosis.The vertebral artery flow voids appear to be intact. Paraspinous soft tissue structures appear within normal limits.Brachial Plexus:Subtle increased T2 hyperintensity is noted involving the C8 nerve root which is favored to be related to the stenosis more proximally in the right C7-T1 neural foramen. Otherwise, remainder of the brachial plexus nerve roots and more distal trunks, divisions, and cords are symmetric in signal and caliber with no abnormal T2 signal or enhancement. No neck masses to suggest compression.
1. Degenerative changes in the cervical spine as detailed above with moderate right neural foraminal stenosis at C7-T1 related to combination of disc material and uncovertebral hypertrophy. There is suspected impingement of the right C8 nerve root. Additional level findings as above.2. No high-grade spinal canal stenosis, cord compression, or cord signal abnormality.3. Subtle T2 hyperintensity/edema involving the proximal right C8 nerve root likely related to stenosis proximally in the neural foramen. Otherwise remainder of the brachial plexus is unremarkable.
