Answer for CoW 25 December 2016
RHEUMATOID ARTHTITIS SHOULDER
Findings
Significant articular cartilage loss with joint space reduction, subchondral erosions and edema noted in the glenoid rim and the adjoining humeral head. Patchy STIR hyperintensities are also noted in the superior humeral head.
Discussion
Features are consistent with inflammatory arthritis (Rheumatoid arthritis). This lady was diagnosed as rheumatoid arthritis and presented with left shoulder pain . In contrast to osteoarthritis , where osteophytes and sclerosis predominate , erosions , synovial thickening and osteopenia occur with inflammatory arthritis . Uniform synovial thickening, large size of bone erosion, rim enhancement at site of bone erosion, and extraarticular cystic masses were more frequent and more numerous in tuberculous arthritis. Nonuniform and greater degree of synovial thickening was more frequent in RA.
