Fig. 21From: Fasciae of the musculoskeletal system: normal anatomy and MR patterns of involvement in autoimmune diseasesContrast-enhanced fat-suppressed T1-weighted (a) axial image of the hands and (b) coronal reformat of the left hand of a 30-year-old female with seropositive non-erosive rheumatoid arthritis. MRI demonstrates inflammatory changes of the distal myo-tendinous junctions of the first dorsal interosseous muscles (arrows). Lack of synovitis suggests primary inflammatory involvement of the myo-tendinous junction. Tenosynovitis of the flexor digitorum tendons is also seen (arrowheads)Back to article page
