ABSTRACT
Psoriatic arthritis is one of the spondyloarthritis. It is a disease of clinical heterogenicity, which may affect peripheral joints, as well as axial spine, with presence of inflammatory lesions in soft tissue, in a form of dactylitis and enthesopathy. Plain radiography remains the basic imaging modality for PsA diagnosis, although early inflammatory changes affecting soft tissue and bone marrow cannot be detected with its use, or the image is indistinctive. Typical radiographic features of PsA occur in an advanced disease, mainly within the synovial joints, but also in fibrocartilaginous joints, such as sacroiliac joints, and additionally in entheses of tendons and ligaments. Moll and Wright classified PsA into 5 subtypes: asymmetric oligoarthritis, symmetric polyarthritis, arthritis mutilans, distal interphalangeal arthritis of the hands and feet and spinal column involvement. In this part of the paper we discuss radiographic features of the disease. The next one will address magnetic resonance imaging and ultrasonography.

Mentions: The 1966 New York grading system is used to evaluate sacroiliitis on radiographs(3, 18, 19). Primarily cortical bone layer is ill-defined with shallow erosions and subchondral osteosclerosis. Secondarily, with the greater amount of erosions, the bone surface gets uneven and unequal joint space widening occurs. Bony proliferations lead to bony bridges, joint space narrowing, and occasionally ankylosis(3) (Fig. 5).
