Davy, I am very sorry that you are having to go through that confusion. Unfortunately what happens at times is that there is a difference between the sensitivity in the testing equipment used in the two locations or in the tests used themselves. Some tests performed give better results than others. Some equipment is more powerful and can detect lesions that others cannot. That may be what has happened in this situation. My suggestion would be (to settle the question for yourself) ask for a copy of both tests results, get the MRI on disc and the print out of the LP, and take them to an MRI radiologist who regularly reads MS tests; someone who actually knows what should or should not be there. Have him look at both discs and tell you (your doctor) what his conclusion is. Not all doctors and equipment are skilled at diagnosing MS. So if your symptoms say MS, you have two priors that say MS, and only one that says it's not but the symptoms are still there, then the issue may be equipment or whose reading the disc.
