69-year-old female with history of pain. ROTATOR CUFF: There is a complete tear of the supraspinatus tendon with retraction to the level of the glenohumeral joint. There is moderate fatty atrophy of the supraspinatus muscle (Goutallier Stage 3). There is a near-complete to complete tear of the infraspinatus tendon with retraction of the majority of the fibers to the medial aspect of the humeral head. There is severe fatty atrophy of the infraspinatus muscle (Goutallier stage 4). The teres minor can be traced to its insertion on the humeral head, although there is increased signal intensity within and along its fibers which may represent partial thickness attritional tearing. There is also a full-thickness tear of the subscapularis tendon with retraction of the superior fibers to the level of the coracoid. Some of the inferior fibers of the tendon can be traced to their insertion on the humerus. The coracohumeral interval measures 5 mm. There is severe fatty atrophy of the superior portion of the subscapularis muscle.SUPRASPINATUS OUTLET: Moderate osteoarthritis affects the AC joint. There is a trace amount of fluid within the subacromial/subdeltoid bursal. The acromiohumeral interval is markedly narrowed. There is a small ossicle along the anterior margin of the acromion process. GLENOHUMERAL JOINT AND GLENOID LABRUM: The humeral head is high riding. Mild osteoarthritis affects the glenohumeral joint. There is increased signal intensity and blunting of the superior labrum likely representing degeneration and tearing. The inferior labrum is grossly intact.BICEPS TENDON: The tendon of the long head of the biceps is visible anterior to the proximal humeral diaphysis with abnormal signal intensity within its substance indicating tearing. We suspect the tendon is completely ruptured more proximally as we do not see it within the rotator cuff interval.
Massive rotator cuff tear and other findings as above.
