Accordingly, the authors offer diagnostic insights in order to improve the approach to the patient’s medical history, clinical examination, and the imaging modalities. Early PsA is a condition with a consistent risk of clinical progression. Marked entheseal involvement is a distinctive clinical aspect that helps discriminate early PsA from other conditions observed at their onset, in particular rheumatoid arthritis.
