question: I also had a Brain MRI stating that I had very minimal FLAIR/T2 periventricular abnormalites...does this mean more than one brain lesion and is it located closer to the spine or brain stem?  I was under the impression it was in the frontal lobe.  I have a cholesterol level of 281, and it has been around 264 for years and had a heart cath 2 years ago which was fine, there was no plaque build up. However, I have had Lyme Disease for close to 7 years untreated now.  I wonder if these lesions are from Lyme Disease.  I do not have MS, unless it is being brought on by untreated Chronic Lyme Disease.I also on the Brain MRI report show Mastoid air cells serated?Impression
