Multiple sclerosis: paresthesias. Brain: There are numerous supratentorial and infratentorial T2 hyperintense white matter lesions, which appear to have slightly increased in extent since 2014. Many of the lesions 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.Spine: There are numerous patchy T2 hyperintense lesions throughout the cervical and thoracic spinal cord. While the usual cervical lordosis is lacking, there is no spondylolisthesis and the 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 is no significant spinal canal stenosis. The paravertebral soft tissues are unremarkable.
