Cramp of limb [729.82] / Pain in limb [729.5] / Sarcoidosis [135] / Brachial neuritis or radiculitis NOS [723.4], Reason for Study: ^Reason: eval for cause of right hand cramping pain x 1 month; hx of abnormal c-spine MRI and neurosarcoid, normal EMG. The cranial-cervical junction is normal. There is normal cervical lordosis. The cervical spine alignment is anatomic. The vertebral body height is preserved. The bone marrow and end plates demonstrate a normal MR appearance. The signal of the visualized cord is normal. Degenerative changes are specified by the intervertebral level as follows: C2-C3: no neuroforaminal narrowing or spinal stenosis. C3-C4: central focal disc protrusion which abuts thecal sac, no change of the degree of disc protrusion since prior scan. C4-C5: central focal disc protrusion which abuts thecal sac, slightly progressed disc protrusion since prior scan. C5-C6: minimal central focal disc protrusion which abuts thecal sac, no change of the degree of disc protrusion since prior scan. C6-C7: no neuroforaminal narrowing or spinal stenosis. C7-T1: no neuroforaminal narrowing or spinal stenosis.
1. Multilevel disc herniations without spinal cord signal abnormality as described above.2. C45 central disc herniation appears to be slightly progressed since prior scan.3. Other levels including C34 and C45 disc herniations do not show any significant interval change since prior scan.
