Wow, thanks for the information. I have known about the "lesions" for about a year or so now. I have always secretly been kind of worried about the lesions being a tumor. My sister had endometrial cancer so I guess I am a little worried about cancer with having a family history of cancer. I have heard of PET scan's being done for questionable "lesions" and to pin point where seizrures are coming from. My neuro said "who knows you may have just been born like that" There was another abnormality chiari 1 malformation. That is where a part of the base of your skull (around where your brain stem is) is longer than normal and extends into the spinal canal. That accounts for balance and equilibrium, which I have always had a problem with. Thank you so much for the info. I see my Dr. tomorrow to switch meds I may ask him about further testing. I hope you have a great day.
