We report a primary synovial osteochondromatosis in a 6-year-old male with a 1-year history of shoulder pain and
stiffness. The patient underwent surgical treatment, resulting in significant improvement in range of motion and
functional status. Primary synovial osteochondromatosis of the shoulder is a rare benign condition that can result in
shoulder pain, stiffness, and locking. MRI helps identify these lesions within the affected joint. Removal of loose bodies
often alleviates symptoms and allows for improved range of motion with satisfactory results.
