 The cervical spine is in normal alignment, with straightening of the normal cervical lordosis. The vertebral body and disk heights are well-maintained. No worrisome focal marrow signal abnormality is appreciated. There is redemonstration of persistent patchy areas of abnormal T2/STIR hyperintensity throughout the cervical cord with associated volume most conspicuous spanning the C2 level and at C4-C5 and C6-C7.There are stable minimal disc bulges at C5-C6 and C6-C7 without stenosis.Partial visualization of left maxillary sinus mucosal retention cyst or polyp. Additional areas of patchy abnormal signal are seen in the upper thoracic cord, incompletely evaluated.LUMBAR SPINE
1.Redemonstration of scattered cord lesions with associated volume loss consistent with chronic demyelinating disease. No definite new cervical cord lesion.2.Interval significant regression of previously identified left paracentral/foraminal disc extrusion at L5-S1, with now only minimal shallow central disc protrusion remaining and no significant stenosis at any level.3.Stable appearance of right foraminal/far lateral prominence of the disc bulge at L4-L5 which abuts the exiting right L4 nerve root. Slight asymmetric enlargement suggested of the exiting nerve root which may indicate inflammatory change. Please correlate with patient's symptoms.
