The definition and assessment of axPsA can be problematic because no agreement and no definitive data on this topic have been published, resulting in uncertainty as to the best approach to deal with these patients. A few recent scientific reports show new data on the possible coincidence of diffuse idiopathic skeletal hyperostosis and axPsA, as well as on the radiological assessment as measured with the validated instruments for axPsA. Moreover, the role of magnetic resonance imaging has also been evaluated for this intriguing subset. All data confirmed that radiological assessment is a useful tool to detect typical findings of axPsA, while other imaging techniques remain to be validated. Finally, there is no evidence to support treatment of axPsA with traditional disease-modifying antirheumatic drugs, while a “leap” to biologic agents is the only treatment after failure with nonsteroidal antiinflammatory drugs.
