Like Butterflake said both CNS Lupus and MS can cause white spots on the brain. The fact that they did a lumbar puncture, they are looking to rule out MS. I know that when people have white lesions on the brain and then they do a lumbar puncture they are attempting to rule out or prove that someone has MS.
A friend of mine from elementary school found out that she has MS back in the late 1990's. In the beginning she was really having a difficult time getting pregnant and it was determined that her MS was just to active. Once they started her on biologic meds for her MS she started feeling better. She still needed some help with fertility treatments, but now has two beautiful children one of each.
I hope that you do not have either one of the problem that has been mentioned to you. Hang in there while you wait to hear from with the results. Don't give up hope, if you have either one of the issues both disease can be treated and things will improve as soon as you start treatment.
Please let us know how things go for you. Remember, you can always get a second opinion, no mater what. You'll be in my prayers, hang in there.
