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.
X-ray of digits
- The following changes can be found on an x-ray:[1][2][3]
- Bone destructive changes including formation of subchondral cyst and erosions
- Fluffy periostitis
- Ankylosis
- Phalangeal tuft acroosteolysis
- New bone formation: Perisoteal and endosteal bone formation may result in increased bone density of an entire phalanx resulting in so called ivory phalanx.
- Pencil-in-cup deformity (osteolytic lesions) usually involving DIP joints but also affects PIP joints
- Osteolysis and ankylosis both coexists in the same joints of hands and foot
- Enthesitis
- Dactylitis (sausage digit)
- Gross finger deformity
- Arthritis mutilans: It may lead to telescoping of fingers caused by marked bony resorption and the subsequent collapse of soft tissue
- Asymmetrical sacroiliitis
- Spondylitis: Asymmetric paravertebral ossifications and relative sparing of the facet joints
