MRI OF THE RIGHT SHOULDER:
HISTORY: Evaluated for rotator cuff tear, impingement.
Multiplanar images were obtained. Overall, the supraspinatus muscle and tendon are grossly intact. There is some mild high signal on the T2 weighted images in the supraspinatus muscle/tendon inferior to the AC joint suggestive of some mild edema. The marrow signal within the bony structures is unremarkable. Biceps tendon is well located within the groove. The glenoid labrum appears grossly intact. There is some degenerative change involving the AC joint that does cause some inferior impingement on the supraspinatus muscle/tendon. There is some fluid in the region of the subscapularis tendon insertion suggestive of at least a partial tear in this area.
IMPRESSION:
1. There are some degenerative changes involving the acromioclavicular joint that does cause some mild edema on the supraspinatus muscle/tendon.
2. There is some fluid along the insertion of the subscapularis muscle on the humeral head suggestive of at least a partial tear in this area.
3. Supraspinatus muscle/tendon is intact without evidence of an acute tear. There is a slight bit of fluid lateral to the insertion of the supraspinatus tendon on the humeral head. Partial tear or tendinosis is not excluded. A collection of fluid is also seen inferior to the acromioclavicular joint suggestive of some fluid in the subacromial/subdeltoid bursa. The combination of findings may represent partial tear or tendinosis of the supraspinatus muscle/tendon.
MRI OF THE LEFT SHOULDER:
CLINICAL HISTORY: Atrophy.
Multiplanar axial, coronal, and sagittal oblique images were obtained through the left shoulder. Left humeral head retains its smooth contour without findings of any avascular necrosis, contusion or occult-type fracture. The acromioclavicular joint does show some degenerative changes with minimal to moderate inferior spurring. Slight effacement of the supraspinatus muscle and tendon complex as a result of the mild impingement. The coronal images through the rotator cuff, however, do not show any abnormal signal changes or evidence of a tear. No retraction. No indication of any joint effusion. The superior and inferior lips of the glenoid labrum are unremarkable. Anterior and posterior lips are also unremarkable. Biceps tendon does not show any subluxation.
IMPRESSION: No indication of any occult-type fracture or bone contusion. Mild impingement of the supraspinatus muscle and tendon complex due to the inferior spurring from the acromioclavicular joint. Intact glenoid labrum. Intact biceps tendon without evidence of subluxation.
MRI OF THE RIGHT SHOULDER:
HISTORY: Pain, wire in shoulder.
Multiplanar images were obtained. The right humeral head is high riding, nearly touching the acromion. There is no normal-appearing supraspinatus muscle or tendon in the field of view. Presumably, the supraspinatus tendon is torn and retracted. There is some minimal fluid in the glenohumeral joint. There is slight deformity to the right humerus, presumably related to an old fracture. There is some metallic artifact due to the wire in this shoulder. The biceps tendon is not well located.
IMPRESSION:
1. Extremely high riding right humeral head with no space between the humeral head and acromion. Supraspinatus muscle and tendon are not intact. The muscle is not included in the field of view. Presumably, there is a tear of the supraspinatus tendon with retraction. This may well be old, as the patient has had prior trauma to the right humerus. There is deformity of the right humerus and resultant metallic artifact from the wire.
2. The biceps tendon is not well located in the biceps tendon groove. There is some distortion of the normal anatomy due to the prior trauma. There is some fluid in the glenohumeral joint.
