MSUS showed no signs of synovitis at the tibiotalar joint (a), and allowed detection of a hypo-anechoic halo around the medial tendons (b) and pathologic vascularization on power Doppler along both the posterior tibialis tendon (c) and the common flexor digiti tendon (d), indicating flourishing tenosynovitis.
