In brief: See below

Synovitis occurs in rheumatoid arthritis and most of the other so called inflammatory arthritides.
The synovium is the sac that surrounds our joints. In synovitis it becomes inflamed and thickened and this is what causes the symptoms of rheumatoid arthritis. This is caused by a malfunction of our immune system which produces antibodies which attack the synovium.

In brief: Other way around

Synovitis is simply inflammation of the synovium which is the lining cell layer of the joint. When synovitis occurs, the lining cells multiply and produce substances that perpetuate the inflammation. Many diseases such as gout , pseudogout, psoriatic arthritis, and even osteoarthritis have varying degrees of synovitis.
