Male 23 years old with left shoulder pain. ROTATOR CUFF: No significant abnormality noted.SUPRASPINATUS OUTLET: No significant abnormality noted. Trace fluid within the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: Linear increased signal intensity partially separates the posterior glenoid labrum from the underlying glenoid. This starts at the 7 o'clock position and extends to the 10 o'clock position and is suspicious for a partial thickness tear but the clinical significance is uncertain. Furthermore, there is low signal intensity situated between the anteroinferior aspect of the glenoid and the humeral head which appears continuous with the capsular structures of the axillary recess and may represent redundant or displaced capsule between the humeral head and glenoid (series 5, image 11). There is also increased signal intensity within the adjacent inferior labrum and we cannot exclude the possibility of additional tearing. Given the limitations of this non-arthrographic study the anterior and superior labrum appear normal. The glenohumeral joint alignment is normal. There is no joint effusion. The articular cartilage appears normal. BICEPS TENDON: The tendon of the long head of biceps is normal.
1. Findings suggestive of incomplete tear of the posterior labrum of questionable clinical significance.2. Possible redundant and/or displaced capsular structures of the axillary recess between the humeral head and glenoid labrum, perhaps associated with adjacent inferior labral tearing. This can be further evaluated with MR arthrography if clinically warranted.
