Hallmark of rheumatoid arthritis are:[1]

- This is an early finding in the course of rheumatoid arthritis.
- Soft tissue swelling is fusiform and periarticular results from of joint effusion, edema, and tenosynovitis.
- Joint space narrowing can be symmetrical or concentric.
- Marginal erosions can result from the erosion by pannus of the bone also called as “bare areas”
