Rotator Interval Tear (MR).

Imaging Protocol: 

The following imaging pulse sequences were performed for the shoulder joint in a high field MR magnet. 
Proton Density fat saturated images in the coronal, sagittal and axial planes. 
Coronal T2 weighted images and sagittal T1 weighted images. 

Findings: 

Revealed:

-Osteoarthritis of acromion clavicular joint.
-A small cystic structure in the neck of the humerus of about 5.8 mm in diameter.
-Degeneration of the tendon of supra spinatous muscle.
-Sub coracoid fluid collection and also fluid collection in the rotator interval.
-Mild fluid collection around tendon of long head of Biceps.

-The Bones alignment and marrow signal: Normal.
-The Muscles surrounding the shoulder joint. Normal.
-The ligaments and other soft tissues: Normal.

Impression: 

• Acromio-clavicular joint osteoarthritis. 
• Degeneration of supra spinatous tendon.
• Evidence of fluid collection in the sub coracoid bursa suggestive of coracoid bursitis. Coracoid bursitis is present in rotator cuff tear and rotator interval tear; in absence of the former in this case; our diagnosis should be the latter.
