Early psoriatic arthritis: the clinical spectrum.

Abstract

Bone scintigraphy yields a more accurate evaluation of entheso-articular involvement and distribution in patients with early PsA. Our results suggest that clinical oligo-enthesoarthritic presentation of early PsA might represent in most cases a polyarticular condition that is at increased risk for clinical progression. These findings have a significant influence on the clinical decision-making process in patients with early PsA.
