Figure 4 Preoperative imaging studies. (A) Ultrasonography reveals multiple hypoechoic rice bodies (red arrows) with mobility on compression in the subacromial bursa. (B) Color Doppler imaging demonstrates absence of blood flow signals within the rice body clusters. (C) Anteroposterior radiograph demonstrates osteosclerotic changes (red rectangular box) at the greater tuberosity without joint space narrowing.
