History of multiple sclerosis, new Lhermitte's sign Again seen are multiple foci of T2 hyperintensity throughout the cervical cord consistent with known demyelinating disease. Relatively more prominent discrete lesion is seen at the right dorsal C3-C4 level and is unchanged. There is mild associated volume loss. Some of the lesions appear slightly more prominent than on the prior study which is favored to be related to subtle differences in technique. For example right paracentral C5-C6 lesion appears more prominent but present previously. No new lesion is definitively appreciated. No lesion with enhancement is seen to suggest active demyelination.Craniovertebral junction appears within normal limits. The cervical vertebral bodies are appropriate in height. Alignment is maintained. Bone marrow signal is within normal limits. Mild degenerative changes are again seen in the cervical spine including multilevel disc desiccation and minimal disc bulges. There is no significant spinal canal or neural foraminal stenosis at any level.
Multiple T2 hyperintense lesions throughout the cervical cord consistent with chronic demyelinating disease. Allowing for slight differences in technique, no new lesion is definitively appreciated. There is no abnormal enhancement to suggest active demyelination.
