Multicenter Study
Ultrasound characterization of ankle involvement in Löfgren syndrome.
Bilateral ankle arthritis is a classic diagnostic criterion for Löfgren syndrome. The objective of this study was to use ultrasonography to characterize the articular and periarticular involvement of the ankles in patients with Löfgren syndrome. ⋯ Contrary to the classical view, our results indicate that ankle involvement in Löfgren syndrome is more often abarticular than articular. The inclusion of bilateral ankle arthritis among the diagnostic criteria for Löfgren syndrome deserves reappraisal.
