Description

The shoulder joint is a relatively rare site for loose bodies of the synovium. In this study we present two cases with loose bodies in the bursa around the shoulder joint.<br>Case 1: A 42-year-old male who had swelling and discomfort with limitation of motion of the right shoulder. Roentgenogram and CT scan showed destruction of the acromion and retention of fluid on the subacrominal brrsa. Operative findings revealed numerous loose bodies. A definite diagnosis of tuberculous bursitis was revealed by histological examination due to the presence of granulation and caseous necrosis.<br>Case 2: An 88-year-old female had been suffering from right shoulder pain for 7 years. Roentgenogram showed numerous radiodense bodies in the right shoulder joint. CT scan and MRI also revealed the same findings. Numerous loose bodies removed from the shoulder were found to be a combination of cartilage and bony tissue. Histologically, this case was diagnosed as synovial osteochondromatosis.<br>In both cases, the lesion was treated by removal of the loose bodies and a partial synovectomy with satisfactory results. From this study, it can be concluded that in cases with loose bodies around the joints, the final diagnosis can be made after histological examination.
