MRI Shoulder

Comparison radiographs: None.

Technique: MRI of the shoulder was acquired in a 1.5 tesla magnet after the administration of intra-articular gadolinium. Three planes of fat-suppressed fast spin echo T2, sagittal T1, as well as axial and oblique coronal fat-suppressed T1-weighted images were acquired.

Findings:
There is no evidence of acute injury at the acromioclavicular joint.
There are hypertrophic changes as well as erosions in the distal clavicle.

The rotator cuff muscles have normal signal.
There is no evidence of a full-thickness rotator cuff tendon tear.
Intermediate signal in the distal infraspinatus tendon is consistent with tendinopathy.

The biceps tendon is abnormally thickened near the supraglenoid tubercle.
Increased signal is also seen within the proximal portion of the tendon.
There is no evidence of displacement.
The extra-articular portion appears normal.

There are no peri-labral cysts.
The anterior-inferior labrum is torn.
There is some medialization of the soft tissues.
The fluid sensitive sequences do not have evidence of edema suggesting this may be a chronic injury.
The superior labrum has abnormal increased signal at and posterior to the origin of long head of the biceps tendon.

In the dependent posterior portion of the capsule is a filling defect which measures approximately 3 x 2 x 7 mm in size.
No large cartilage donor site is appreciated.

Impressions:
1. Chronic anterior-inferior labral tear.
2. Superior labral tear with extension into long head of the biceps tendon versus associated biceps partial tear.
3. The filling defect in the posterior capsule concerning for intra-articular body. Recommend correlation with radiography.
4. Acromioclavicular joint arthropathy and rotator cuff tendinosis.
