Fluid collections and juxta-articular cystic lesions of the shoulder: spectrum of MRI findings.

摘要

The MR imaging features of fluid collections and juxta-articular cystic lesions of the shoulder are discussed, with special focus on those related to subacromial impingement and rotator cuff tears. Other more unusual fluid collections and cystic lesions are described, including rice-bodies bursitis, idiopathic synovial osteochondromatosis, dialysis-related amyloid arthropathy, hemophilic arthropathy, infectious conditions, non-infectious inflammatory arthritis, and paralabral cysts.
