History of MS, with brain and spinal cord lesions. Brain: There are numerous supratentorial and infratentorial T2 hyperintense lesions. Many of the lesions are also T1 hypointense, but small lesions in the left corona radiata and peritrigonal white matter demonstrate enhancement. There is no evidence of intracranial hemorrhage or mass. 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 in the cervical spinal cord and perhaps in the conus medullaris region. The thoracic spinal cord otherwise appears to be relatively spared. There is no evidence of enhancing lesions in the spinal cord. There is no spondylolisthesis. 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.
Numerous intracranial and spinal cord demyelinating lesions, with acutely inflamed lesions in the left corona radiata and peritrigonal white matter.
