Summary: | 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. |
