Axial ultrasound image of the flexor tendons at the level of the left medial malleolus (MM), showing hypoechoic fluid around the tibialis posterior tendon (TP) and the flexor digitorum longus (FDL) tendon, in keeping with tenosynovitis. There are also extensive subcutaneous small fluid collections consistent with subcutaneous edema/cellulitis

Longitudinal ultrasound image with color Doppler of the tibialis posterior tendon (T) at the level of the left medial malleolus (MM). There is effusion (asterisk) in the tendon sheath, consistent with tenosynovitis. There are also subcutaneous small fluid collections (arrow), in keeping with fat cellulitis, and increased vascularity of the subcutaneous fat consistent with acute inflammation
