34 years, Female, multiple sclerosis, evaluate for progression. Brain: Again seen are several scattered supratentorial foci of subcortical and periventricular T2/FLAIR hyperintensity compatible with known demyelinating disease. These are not significantly changed since 11/26/2014. No infratentorial lesions are appreciated. No new lesions. No lesions with enhancement. No intracranial mass or mass effect. Brain parenchymal volume is preserved. There is mild mucosal thickening involving the bilateral maxillary and right frontal sinuses and was present previously. The calvarium and extracranial soft tissues are unremarkable.Cervical spine: Cervical spine sequences are motion degraded slightly limiting evaluation. Again seen is a T2 hyperintense lesion in the dorsal aspect of the cervical cord at the C4 level, and is less conspicuous in the interval. There is intrinsic T1 hyperintensity without definite enhancement. There is a questionable T2 hyperintense lesion in the left aspect of the cord at the C7 level without corresponding abnormality on sagittal STIR or T2 sequences and may be artifactual. No new lesions or lesions with enhancement in the cervical cord are definitively appreciated. Vertebral body heights and alignment in the cervical spine are maintained. Bone marrow signal is benign. There is no significant spinal canal or neural foraminal stenosis. Paraspinous soft tissues are unremarkable.
Several T2 hyperintense lesions involving the supratentorial white matter as well as in the cervical cord at the C4 level are consistent with known chronic demyelinating disease. No evidence of new lesions in the brain or cervical spine compared to 11/26/2014. No abnormal enhancement to suggest active demyelination.
