I have not ever heard of a meningeoma associated with MS. You might go to the National MS Society website and do a search (www.nmss.org) and see if there is anything there.
The only time I get swelling of the hands and face, related to having MS, is when I've been on a dose of steriods...which I haven't used for years, now.
I do get swollen feet and ankles, primarily because I'm in a wheelchair and sit all the time, disruupting the normal blood (and other body fluids) flow, from feet back to the head and through the body. about the only t hing that helps that is to sit or lie down with my feet elevated.
MS lesions are not generally described as "tumors". They're a scarring of the myelin sheath, the outer covering, of the nerves. Most often they occur in the brain, in specific areas of the brain, but also can occur on the spinal cord. But they would look quite different than a tumor on an MRI.
