A "non bony" Bankart lesion and a type V SLAP tear are clearly seen.
The axial views show
- superior extension of the anterior labral tear (reaching 12 o'clock) with contrast leakage into the subscapularis space and subcoracoid bursa. Note the middle glenohumeral ligament is normal
- the humeral head cyst and a reversed Hill-Sachs lesion are present. No contrast leakage into bicipital tendon
- the PD images also demonstrate normal cartilage covering the humeral head and glenoid bone
- abnormal increased signal intensity of subscapularis tendon is noted at its myotendinous junction. No definitive tear could be seen in other rotator cuff muscles
Coronal views show
- leakage of contrast from the joint space into the humeral bone cyst suggesting presence of an intraosseous synovial cyst
- the axillary pouch looks OK and the inferior glenohumeral ligament is normal
- the fluid signal of the subacromial bursa is present with no definitive contrast leakage through the supraspinatus tendon
- no definitive tear in the supraspinatus or infraspinatus tendons
- the signal of fluid inside the subacromial bursa is mostly related to bursal effusion rather than to contrast leakage. unfortunately, post-injection T1 image was not done to confirm
Sagittal views show
- no apparent rotator cuff tear could be seen except some contrast signal in the subscapularis myotendinous junction
- the labral tear appears to start at 5 o'clock of the anterior labrum and extends superiorly with no bone involvement of labral sleeve, suggesting presence of a Bankart lesion
