That description of the increased signal intensity in the subcortical white matter is how a radiologist will typically describe what we all refer to as lesions. My reports are very similar to yours in that there are a number of possible causes for the enhanced signal on the MRI, and they arrive at an MS Dx usually based on descriptions of symptoms, and the results of other testing that rules out other possible causes.

My question is why do you think you have a cause of action against the Dr and why do you need financial redress for it? Do you think the doctors deliberately mis Dxed you? Did you lose alot of money because you were Dxed? MS and other non-specific disorders are extremely hard to Dx and the testing required to rule things in or out can be very expensive. So the docs have to balance the cost and time and trouble to the patient of doing more tests against the value of ruling out one more possible thing. If all of your symptoms are leading the doctor towards MS, and the MRI shows a possible lesion, it is not unreasonable for them to lean towards that Dx, and to shy away from doing other expensive tests that might not give them any information they didn't already have. Until there is a yes or no test for MS, there will be times when the doctors are wrong. Just because they are wrong, doesn't mean they were guilty of malpractice. If they make the best Dx based on the info they have and it is wrong...it is just wrong...not malpractice. Not directing this at you entirely, but if people want to have lower medical costs, a great place to start is accepting that doctors are not infallible, and when they are wrong, it isn't always cause for a lawsuit.

Ok, sorry, off my soapbox now...
