Fig. 1. Magnetic resonance imaging showed cystic fluid collection adjacent to the biceps tendon insertion at the right radial head. There was a signal change in the biceps tendon near the bicipitoradial bursa beneath the brachioradialis muscle and a thick peripheral rim enhancement in post-contrast images (A). Ultrasonography defined a bicipitoradial bursa measuring 1.7×1.2 cm (B). Two weeks later, the enlarged bursa had completely disappeared in ultrasonography (C). r: radial head, b: brachioradialis muscle, arrowheads: bicipitoradial bursa.
