The ultrasound of the left knee joint reveals mild joint effusion and mild diffuse synovial thickening with minimal internal vascularity of power Doppler, suggesting active synovitis.
Case Discussion
The rheumatoid factor and ENA profile of the patient were negative, and HLA-B27 was positive. The ESR and CRP were high.
The patient had significant improvement in her symptoms after steroid therapy.
