US images show supraspinatus calcification in a 37-year-old man. (a) Calcific deposit (C) can be clearly seen with moderate acoustic shadowing (circles). Subacromial bursitis (arrow) can be seen. (b) End of treatment. Most calcific material was removed from calcification (?) with double-needle procedure. Only a thin calcific wall (arrowheads) was left. Needles (arrows) are still inside calcification. H = humeral head.
