 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. CERVICAL SPINE
1.No abnormal signal or pathological enhancement of the brain or spinal cord to suggest demyelinating disease. 2.There is new disc desiccation and disc height loss with mild disc bulge at L4/5 without significant resulting stenosis.3.Note that although there are no new gross abnormalities of the optic nerves, full characterization would require orbital MRI with contrast.
