Multiple sclerosis, weakness, leg. Follow-up for progression. Cervical: There is a discrete T2 hyperintense lesion involving the left dorsal aspect of the cord at the C7 level which is seen on the sagittal STIR as well as axial T2 sequences. There are additional tiny punctate lesions at the right ventral C3 and right ventral C6 levels seen on both the axial T2 and mFFE sequences likely representing additional demyelinating plaques. There is possible additional tiny lesion at the left anterior cord at the upper C4 level.Vertebral body heights and alignment in the cervical spine are normal. There is no significant disc disease or spinal canal or neural foraminal stenosis at any level. Bone marrow signal is benign. Paraspinous soft tissues are unremarkable.Thoracic: There is a discrete T2 hyperintense lesion involving the left dorsal cord at the left T11-T12 level. Otherwise no additional lesion within the thoracic cord is definitively appreciated. Thoracic vertebral body heights are maintained. Alignment is maintained. No significant spinal canal or neural foraminal stenosis is seen. Bone marrow signal is benign with no suspicious lesions. Paraspinous soft tissues are unremarkable.
There are at least three T2 hyperintense lesions in the cervical cord, relatively more prominent at the left dorsal C7 level. There is also a thoracic cord lesion at the left T11-T12 level. Findings are compatible with known history of demyelinating disease. An addendum can be made to prior studies if available.
