 BRAIN: There are at least 15 white matter T2 hyperintense lesions in the bilateral cerebral white matter, and in the left midbrain. There is a mildly worsened left cerebral peduncle T2 hyperintense lesion on series 601 image 32. There is a T2 hyperintense lesion in the right periatrial white matter on series 601 image 45 which also appears mildly worsened. There are two new T2 hyperintense lesions in the left periatrial white matter on series 601 image 48. There is a new right inferior frontal white matter T2 hyperintense lesion on series 601 image 41. There is a new left superior frontal gyrus white matter T2 hyperintense lesion on series 601 image 59. The remaining white matter lesions are unchanged. Only one new left periatrial white matter lesions enhances suggesting active demyelination. The ventricles and sulci are unchanged.CERVICAL: Multiple patchy areas of ill-defined high T2 signal within the imaged portion of the cervical cord are again seen. There is a stable anterior medulla T2 hyperintense lesion. The lesion centered at C2 level appears slightly less prominent compared to the prior exam in craniocaudal extent. The lesion along the dorsal right aspect of the cord centered at C3-4 level appears smaller. No definite new lesion is identified in the cervical cord. There is no pathologic enhancement of the white matter lesions in the cord. The osseous marrow signal is benign. The alignment is within normal limits. There are mild multilevel degenerative changes with disk osteophyte complexes most prominent at C4-5 and C5-6 without significant spinal canal stenosis or neural foraminal stenosis.
1.Numerous (greater than 15) T2 hyperintense white matter lesions in the brain with multiple new lesions and a few worsening lesions. A single left periatrial white matter lesion enhances suggesting active demyelination.2.Multiple patchy areas of well-defined high T2 signal in the imaged cervical cord again seen slightly less prominence of the lesion centered at C2 level. No definite new cervical cord lesion or pathologic enhancement.
