Gross swelling and hypoechoic, heterogeneous appearance of the tendon of flexor carpi radialis (FCR)muscle can be noted at the site of the insertion (at least 3 times more swollen than the contralateral side) in keeping with chronic tendinosis. Hypervascular thickening of the peritendinous soft tissues are also noted in keeping with peritendinitis. These findings are congruent with the recent symptoms (painful flexion).
