File:Acromioclavicular joint injury with muscle injuries (ultrasound) (Radiopaedia 80623).jpg

Summary:

• Radiopaedia case ID: 80623
• Image ID: 53216491
• Modality: Ultrasound
• System: Musculoskeletal
• Findings: The right acromioclavicular joint shows hypoechoic thickening of the capsule and synovium resulting in mild widening of the space in comparison to the contralateral left joint. However, there is no subluxation/ dislocation. The rotator cuff is intact and shows normal echopattern. There is no effusion in the glenohumeral joint or subacromial-subdeltoid bursa. The trapezius muscle and the anterior head of the deltoid muscle show a focal ill-defined area of loss of normal muscle echopattern with the presence of tiny fluids. However, there is no large defect in either of the muscles. The subcutaneous fat overlying anterior head of the deltoid muscle shows increased echogenicity and fluid clefts.
