Female, 31 years old, with right-sided ataxia and weakness, new diagnosis of MS, looking for progression from the prior MRI. Brain:Multiple round, oval and linear foci of T2 hyperintensity are demonstrated in the corpus callosum and periventricular tissues. Somewhat confluent signal abnormality is evident in the periatrial regions. Scattered additional focal lesions are demonstrated to a lesser extent in the brainstem, at the left trigeminal root entry zone, and along the right superior cerebellar peduncle. None of the lesions visualized on today's examination demonstrates clear evidence of enhancement.On comparison with the prior study, at least one lesion is new, this in the right frontal subcortical region (image 33 series 401). There may be additional smaller new lesions, but differences in technique between the two studies to make accurate comparison difficult. No evidence of significant mass effect is seen. Brain parenchymal volume is maintained. No abnormal extra axial fluid collections are seen. The ventricles are normal in size and morphology.Cervical spine:No evidence of any focal spinal cord lesion is seen. No pathologic intramedullary or leptomeningeal enhancement is detected. There are no epidural abnormalities.Spinal alignment is anatomic. Vertebral body height and morphology are within normal limits. Marrow signal characteristics are remarkable.A posterior disc osteophyte complex at C5-6 effaces the ventral thecal sac but causes no significant generalized spinal canal stenosis. This finding is unchanged. The intervertebral discs are otherwise preserved. No areas of significant spinal canal or foraminal narrowing are detected.
1.Numerous parenchymal lesions are identified compatible with the history of multiple sclerosis. At least one lesion in the right frontal lobe is clearly new from the prior examination.2.No evidence of any demyelinating lesions in the cervical spinal cord.
