MRI of the pelvis and sacroiliac joints. Coronal T1-weighted (a) as well as (b) fat-saturated (FS) post IV contrast images of the pelvis and sacroiliac joints; showing a 5 cm in diameter multiloculated collection showing dense marginal enhancement deep to left iliopsoas muscle communicating with underlying left sacroiliac joint cavity (see arrow) with evidence of left sacroiliitis in the form of irregular articular surface with subarticular thickening as well as enhancement.

MRI of the right shoulder joint. Coronal T1-weighted (a) and (b) (FS) after IV contrast images of the right shoulder showing dense enhancement of a markedly thickened shoulder joint synovium as well as the subacromial and the subdeltoid bursae with joint effusion is noted. A focal 1 cm area of erosion and underlying trabecular bone enhancement in the greater tuberosity of the humerus and a full thickness tear of supraspinatus tendon with enhancing edges are evident. There is also associated degeneration of the acromioclavicular joint with hypertrophy of its capsule.
