Standard ultrasound scan of the feet showed bilateral multiple fairly well-defined heterogeneously hypoechoic cutaneous/subcutaneous nodules. The largest nodule is seen around the left ankle joint, which measures 3.33 × 0.72 cm (a). The similar smaller lesion seen in the dorsum of the left measures 2.20 × 0.79 cm, with no evidence of extension to deep structures and no internal vascularity or calcifications (b). These nodules are of non-specific sonographic appearance
