41-year-old female with multiple sclerosis, leg weakness, evaluate for progression. Brain: Redemonstrated are numerous supratentorial and infratentorial T2 hyperintense white matter lesions, without definite new lesion. Many display T1 hypointensity. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable. There is new mild mucosal thickening within the ethmoid air cells. The remainder the paranasal sinuses and the mastoid air cells are clear. Expected vascular flow voids are demonstrated.Thoracic Spine: Redemonstrated are nonenhancing T2 hyperintense lesions throughout the thoracic spinal cord, unchanged in appearance, with the most prominent lesion noted at the T9 level. There are no new lesions. Thoracic vertebral column alignment is within normal limits. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. There are no stenoses. The paravertebral soft tissues are unremarkable.
1.Numerous cerebral supratentorial and infratentorial demyelinating lesions are stable without definite new lesion. 2.Stable nonenhancing demyelinating lesions of the thoracic spine.
