Overview

An x-ray may be helpful in the diagnosis of psoriatic arthritis. Findings on an x-ray suggestive psoriatic arthritis include bone erosion, characteristic "pencil-in-cup" deformities and proliferative changes. Psoriatic arthritis may also lead to periostitis, dactylitis, or arthritis mutilans.
