We report a rare case of synovial osteochondromatosis in bilateral subacromial bursae. A 73-year-old man presented with sudden shoulder pain. Roentgenograms showed a large number of calcifications between the acromial processes, and a greater tuberosity on both sides. Surgery was performed to remove loose bodies from both sides. There were 11 in the right subacromial bursa, and 9 in the left. According to Milgrams staging system, this case was diagnosed as stage III. A follow-up examination 10 months after the operation found no recurrence, pain, or limitation of the range of motion on either side.
