64-year-old female with a soft tissue mass present for 30 years. A marker was placed on the posterior aspect of the shoulder. Deep to this marker is a predominantly fatty mass within the subcutaneous fat measuring 5.3 x 4.3 x 3.5 cm (TR x AP x CC), although accurate measurement is difficult due to lack of contrast with the adjacent subcutaneous fat. There are thin septations within this mass that show minimal, if any, enhancement. This is most compatible with a lipoma. Please note that this study was not protocoled for detailed evaluation of the rotator cuff, however, there is a full-thickness tear of the anterior fibers of the supraspinatus measuring approximately 1 cm in the AP dimension. There is perhaps mild fatty atrophy of the supraspinatus muscle. Severe osteoarthritis affects the acromioclavicular joint with a mild synovitis. There also appears to be a mild synovitis of the glenohumeral joint.
1. Subcutaneous lipoma.2. Full-thickness tear of the supraspinatus tendon.3. Osteoarthritis of the acromioclavicular joint. Other findings as described above.
