NMO clinical trial. Orbits: The optic nerves, extraocular muscles, globes, and orbital fat are unremarkable.Brain: There is no evidence of intracranial hemorrhage, mass, or acute infarct. The T2 hyperintensity in the inferior medulla has nearly resolved. The brain parenchyma and cerebellum otherwise appear unremarkable. 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 skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.Spine: There is decrease in the degree of T2 hyperintensity and swelling involving the majority of the cervical and thoracic spinal cord, with a few remaining patchy areas of signal abnormality. The cauda equina nerve roots are unremarkable. The vertebral column alignment is unchanged. 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.
The edema involving the medulla has nearly resolved and the edema in the spinal cord has further diminished.
