 MRI brain:The ventricles and sulci are within normal limits. There is mild global volume loss greater than expected for age but this is nonspecific. The cisterns remain patent. There is no midline shift or mass effect. There are no areas of abnormal signal or pathological enhancement. 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. There is partial opacification of the right sphenoid sinus. MRI T-spine:The thoracic spine is in normal alignment. The vertebral body and disk heights are well-maintained. No worrisome focal marrow signal abnormality is appreciated. The spinal cord is of normal caliber and signal. There is a small T7-8 central disc protrusion but no significant spinal canal or foraminal stenosis within the thoracic spine.
No evidence of a demyelinating process in the brain or thoracic spine. Global volume loss greater than expected for patient's stated age.
