[|Human|] Are there any other illnesses besides MS that are associated with brain lesions? I have had an MRI that showed lesions but my spinal tap came back OK. My neurologist is 90% certain that it s not MS because the spinal tap was OK. I have been having some issues for almost 2 yrs. I have been having pain in my left leg, starting at mid thigh and as it descends down my leg, it turns into more of a numb feeling. It seems to be worse at night. During my exam, my doctor did state that I had diminished sensation on my left side. I have had another set of MRI s down of my neck and spine but I haven t heard back on those yet.
[|AI|]  Hello. I have been through your question and understand your concern. Brain lesions seen in MRI are becoming a common feature and not of all of these are significant. Most of them are benign white matter disease somehow related to blood pressure but not associated to any particular disease, being benign and not troublesome. The symptoms in your leg should in first place be related more than to brain lesions to spine problems like herniated disc or degenerative disc disease. Still, a nerve conduction study is essential in my point of view to better evaluate the degree of nerve involvement. Basically since the spinal tap excluded MS it is quite sure you do not have MS.hope this helps
