 MRI Brain: There are no areas of abnormal signal or pathological enhancement to suggest demyelinating disease. There is unchanged cavum septum pellucidum and vergae. The ventricles and sulci are within normal limits. The cisterns remain patent. There is no midline shift or mass effect. There is no diffusion abnormality. No extra-axial fluid collection is identified.Normal flow-voids are demonstrated in the major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits. MRI Orbits: There may be minimal residual T2 hyperintensity and enhancement involving the prechiasmatic left optic nerve. There is no significant T2 hyperintensity or enhancement involving the right optic nerve, which is otherwise unchanged. The optic chiasm appears to be uninvolved. The globes and extraocular muscles are otherwise unremarkable. MRI Cervical spine: The cervical spine is in normal alignment, with a normal cervical lordosis. The vertebral body and disc heights are well-maintained. No worrisome focal marrow signal abnormality is appreciated. The spinal cord is of normal caliber and signal. There is no pathological enhancement.There is no significant disc bulge, herniation, spinal canal or foraminal stenosis within the cervical spine.
1. Questioned minimal if any residual T2 hyperintensity and enhancement involving the prechiasmatic left optic nerve. No significant interval change in the appearance of the right optic nerve.2. No abnormal signal or pathological enhancement of the brain or cervical cord to suggest demyelinating disease.
