Introduction:
Synovial chondromatosis is a rare metaplastic disorder of the synovial membrane. Primary synovial chondromatosis of the shoulder joint is a rare localization and extra-articular localization around the shoulder is much less common.
Case report:
We report a rare case of a 13-year-old boy with primary synovial chondromatosis of the subscapular bursa. Computed tomography and magnetic resonance imaging showed that multiple cartilaginous loose bodies were found in the subscapular bursa and the glenohumeral joint. Arthroscopic removal of loose bodies and synovectomy of the subscapular bursa was performed through sublabral foramen.
Conclusion:
Pre-operative investigation for the precise location of the lesions was important for the planning the operative procedure. Arthroscopic removal of loose bodies and synovectomy was useful treatment options for synovial chondromatosis of the subscapular bursa.
