Female, 25 years old, with multiple sclerosis and paresthesias. Evaluate for progression. Brain:Multiple T2 hyperintense lesions are redemonstrated within the periventricular and juxtacortical white matter. To a much lesser extent, lesions are also seen in the brainstem and posterior fossa. A periventricular lesion on the left (image 52 series 41) does appear to have increased in size from prior, and there may be two or three very small new periventricular lesions, but this is equivocal and could reflect differences in technique.No evidence of cortical edema or mass effect is seen. The corpus callosum is thinned, particularly posteriorly. The lateral and third ventricles remain enlarged, similar to that seen on the prior examination. No abnormal fluid collections are detected.C-spine:The previously demonstrated ill-defined lesions within the cervical spinal cord are no longer distinctly visualized and no new discrete lesions are demonstrated. The spinal cord demonstrates normal morphology throughout.Straightening of the cervical lordosis may be positional. Vertebral body height and morphology are within normal limits. No evidence of pathologic marrow replacement or edema is seen. The intervertebral discs are preserved. No significant spinal canal or foraminal stenosis is detected.
1.Numerous lesions are redemonstrated in the brain compatible with demyelinating disease. In comparison with the prior examination, one left-sided periventricular lesion may be slightly larger and there are perhaps two or three equivocally new lesions.2.Chronic ventriculomegaly is again seen, similar to prior.3.The previously demonstrated lesions in the cervical spinal cord are no longer clearly seen, and no discrete new lesions are identified
