Reason: MS, f/u progression History: paresthesias Brain:Redemonstration of numerous T2 hyperintense lesions within the periventricular and to a lesser extent subcortical white matter, including within the corpus callosum. There is a single new lesion in the right posterior frontal lobe subcortical white matter (series 501 image 64 and series 801 image 47). This demonstrates mild enhancement compatible with an active lesion.There is no evidence of intracranial hemorrhage, or mass.The ventricles and basal cisterns are normal in size and configuration.The expected intracranial vascular flow voids are present.Right maxillary sinus mucous retention cyst. The visualized mastoid air cells are clear. The orbits are unremarkable.Cervical spine:Again noted are multiple poorly defined long segment foci of increased T2 signal within the cervical spine. There is no associated cord expansion. The vertebral column alignment is within normal limits. The vertebral body and disc heights are preserved. The vertebral bone marrow signal is unremarkable. No significant spinal canal or neural foraminal stenoses.
1. Numerous intracranial white matter lesions compatible with the history of multiple sclerosis. There is a single new right frontal lobe subcortical lesion which also demonstrates enhancement indicating an active lesion.2. Numerous long segment poorly defined intramedullary lesions in the cervical spine compatible with the history of MS. No significant interval change.
