The symptomatic left shoulder shows absent biceps tendon in the bicipital groove. There is no medially dislocated biceps long head tendon. Its myotendinous junction is absent at the level of the pectoralis major tendon insertion. The short head of the biceps brachii is normal. The distal biceps tendon is intact. Supraspinatus, infraspinatus, teres minor, and subscapularis tendons are intact. The supraspinatus tendon shows mild heterogeneous echopattern without fluid cleft / volume loss / calcification. Supraspinatus and infraspinatus muscles show normal bulk and echopattern. There is no subacromial-subdeltoid bursal effusion or glenohumeral joint effusion. There is an ill-defined area of increased echogenicity of the subcutaneous fat over the acromial process of the scapula without any fluid cleft/collection. This correlates with the site of pain and represents fat contusion.
The asymptomatic right rotator cuff was examined. The long head of the biceps tendon is absent in the bicipital groove. There is no medially dislocated tendon. There is absent myotendinous junction of the long head of the biceps under the pectoralis major tendon insertion. The short head of the biceps is normal. Subscapularis, supraspinatus, infraspinatus, teres minor tendons are intact and show normal echopattern. Supraspinatus and infraspinatus muscles are normal. There is no bursal or joint effusion.
