Reason: Demyelinating disease; f/u progression History: paresthesias. MRI brain:Scattered supratentorial T2 hyperintensities are redemonstrated, with significantly decreased size of prominent right parietal and left temporal lesions. Enhancement of the right parietal lesion has resolved. There remains scattered gyriform and subcortical T2 hyperintensities in the bilateral frontal high convexities, right frontal centrum semiovale and right parietal lobe which are unchanged. Mildly prominent ventricles are unchanged. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is no abnormal intracranial enhancement. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.MRI cervical spine:The vertebral column alignment is within normal limits. There is a normal relationship of the dens with the arch of C1. Vertebral body heights are intact. Multilevel disc desiccation. No abnormal marrow signal. Mild posterior disc osteophyte complex at C6-C7, however no significant spinal canal or neural foraminal stenosis. No abnormal signal within the spinal cord. No abnormal enhancement.MRI thoracic spine:The vertebral column alignment is within normal limits. Vertebral body heights are intact. Disc spaces are preserved. No abnormal marrow signal. No significant spinal canal or neural foraminal stenosis. No abnormal signal within the spinal cord. No abnormal enhancement.
1.Significant decrease in size of right parietal and left temporal lobe demyelinating lesions seen on the prior exam with resolution of enhancement. Multiple persistent lesions are present without evidence of new lesions.2.Normal cervical and thoracic spine MRI.
