Female, 47 years old, with multiple sclerosis presenting with paresthesias. Evaluate for progression. Brain:As on the prior examination, approximately five T2 hyperintense lesions are seen involving the periventricular and juxtacortical regions of the cerebral hemispheres. There has been no significant interval change in the size or morphology of these lesions and no new lesions are detected. Lesions in the left superior frontal gyrus and in the bilateral periatrial regions demonstrate corresponding marked T1 hypointensity, similar to prior.No significant parenchymal edema or mass effect is detected. No abnormal extra-axial fluid collections are identified. The ventricles remain normal in size and morphology.C-spine:Patchy spinal cord T2 hyperintensity is seen at the cervico-medullary junction, at the C3-4 level, at the C6-7 level, at the T1-2 level, and perhaps also at the T3-4 level, partially visualized. The lesion at T1-2 is associated with mild cord volume loss indicating chronicity. No prior cervical spine MRI is available for comparison, but the lesions at T1-T2 and T3-4 appear similar to prior.Mild degenerative reversal of the normal cervical lordosis is seen. Sagittal alignment is otherwise unremarkable. Vertebral body heights and morphology are unremarkable allowing for degenerative endplate collapse at C5 and C6. Corresponding degenerative endplate signal change is also seen. No concerning marrow replacement is detected.C2-3: No spinal canal stenosis or neuroforaminal narrowing. C3-4: Minimal posterior disc-osteophyte complex formation. No significant spinal canal or foraminal stenosis. C4-5: No spinal canal stenosis or neuroforaminal narrowing. C5-6: Loss of disc height. Minimal posterior disc-osteophyte complex formation. No significant spinal canal stenosis. Very mild left foraminal narrowing. C6-7: Minimal posterior disc-osteophyte complex formation. No significant spinal canal stenosis. Mild left foraminal narrowing. C7-T1: No spinal canal stenosis or neuroforaminal narrowing.
1.Approximately five white matter lesions are demonstrated within the cerebral hemispheres showing no significant interval change. No new lesions are detected.2.Patchy spinal cord signal abnormality is identified in the cervical region and in the visualized upper thoracic region. No prior cervical spine MR images are available for adequate comparison, but the upper thoracic cord lesions appear similar to prior.
