Title: Commentary on: reporting in axial spondyloarthritis: proposal for an MRI reporting system
Abstract: Spondyloarthritis (SpA) is an umbrella terminology used to describe a group of closely related diseases with a predisposition for inflammatory arthritis of the axial skeleton (spine and sacroiliac joints [SIJs]), as well as peripheral joints. This group includes ankylosing spondylitis (AS), psoriatic arthritis, reactive arthritis, juvenile SpA, arthritis associated with inflammatory bowel disease (enteropathic arthritis), and undifferentiated SpA. AS occurs in about 0.5% of the Caucasian population, whereas the prevalence of SpA as a group is about 1.5–2%. 1 Helmick C.G. Felson D.T. Lawrence R.C. et al.

They also share common clinical features, but the presentation can be quite heterogeneous, including inflammatory back pain (IBP), peripheral inflammatory arthritis, peri-articular manifestations such as enthesitis and dactylitis ("sausage" digits), and extra-articular manifestations such as psoriasis, uveitis, and inflammatory bowel disease.
