Multiple sclerosis [G35], Reason for Study: ^Reason: MS, eval for progression History: gait problems Multifocal bihemispheric FLAIR high signal intensity lesions are again seen.Overall the number and size of lesions do not show any significant interval change since prior scan. However, there are a couple of lesions appear to be more conspicuous on this scan than prior which include left superior temporal gyrus anterior aspect lesion and the lesion just below the left Heschl's gyrus, right mesial temporal lobe. On the other hand, the FLAIR high signal intensity lesion at the right periventricular white matter lesion at anterior aspect of the external capsule especially around the frontal horn appears to be slightly smaller in its extent than prior scan.The ventricles, sulci and cisterns are symmetric and unremarkable. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. Overall stable FLAIR high signal intensity lesions consistent with Multiple Sclerosis.2. Some lesions are more conspicuous on today's scan and another appears to be slightly decreased in its extent since prior scan as described above.
