Unspecified disturbances of skin sensation [R20.9], Reason for Study: ^Reason: cervical myelopathy History: R sided numbness There is broad based disc extrusion at the level of C56 which compressed thecal sac and severely narrows the right side lateral recess.There is normal cervical lordosis. The cranial-cervical junction is normal. The spine alignment is anatomic. The vertebral body height is preserved. The bone marrow and end plates demonstrate a normal MR appearance. The cord signal is normal. There is no evidence of abnormal enhancement, cord compression or mass. Degenerative changes are specified by the intervertebral level as follows: C2-C3: no neuroforaminal narrowing or spinal stenosis. C3-C4: there disc-ligament complex abutting thecal sac which results mild spinal canal stenosis.C4-C5: there is central to slightly right disc protrusion which indents and abuts thecal sac results mild spinal canal stenosis. C5-C6: there is extrusion of disc toward right side neuroforamen results moderate spinal stenosis and significant right lateral recess stenosis. C6-C7: there is broad based disc protrusion central to left laterally which indents thecal sac. C7-T1: no neuroforaminal narrowing or spinal stenosis. T12-L1: no neuroforaminal narrowing or spinal stenosis.
1. Disc herniations at the level of C45, C56 and C67 as described above. Among them, the C56 disc demonstrates disc extrusion which results severe narrowing of the right lateral recess.2. Normal spinal cord signal intensity.
