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: PsA syndesmophytes not always can be differentiated from those appearing in ankylosing spondylitis (AS) due to the presence of the “bamboo” spine in both entities. However, usually an early spine involvement in PsA manifests itself with asymmetric syndesmophytes that are roughly linear or curvilinear, thick, fluffy and parallel to the lateral surface of vertebral bodies and intersomatic spaces(3) that increase in size, defined as defined as parasyndesmophytes or non-marginal, bulky syndesmophytes (Fig. 4).
