Right shoulder pain ROTATOR CUFF: There is increased signal separating the anterior fibers of the distal supraspinatus from the greater tuberosity, indicating an insertional tear. This is best appreciated on the sagittal T2 oblique series. The tear measures approximately 1 cm in the AP dimension and although it appears to involve the majority of the thickness of the tendon, there is no retraction and it may not extend through the articular or bursal surface fibers. There is a small focus of abnormal marrow signal within the underlying greater tuberosity. There is mild tendinosis of the remaining supraspinatus tendon with mild associated fatty infiltration of the muscle distally. The infraspinatus and teres minor tendons demonstrate no evidence of focal tearing or muscle atrophy. Evaluation of the subscapularis is limited by internal rotation however there is no evidence of focal tear or muscle atrophy.SUPRASPINATUS OUTLET: The acromioclavicular articulation is normal. There is a trace amount of fluid within the subacromial/subdeltoid bursa which is of questionable significance.GLENOHUMERAL JOINT AND GLENOID LABRUM: There is mild osteoarthritis and thinning of the articular cartilage of the glenohumeral joint. There is branching intermediate signal within the superior labrum representing tearing. There is deformity of the anterior labrum which is also likely secondary to tearing.BICEPS TENDON: Evaluation of the long head tendon of the biceps is limited given patient positioning however there is no discrete abnormality identified.
Non-retracted and possibly concealed insertional tear of the anterior distal fibers of the supraspinatus. The remaining rotator cuff tendons are intact and additional findings are described above.
