以超音波來診斷肱二頭肌長頭肌腱斷裂之陷阱：病例報告
Abstract
Musculoskeletal ultrasonography is a widely used diagnostic tool to visualize shoulder tendon pathology. The diagnostic accuracy for biceps tendon pathology is high. An empty groove may be seen when there is complete rupture, and the long head tendon markedly retracts into the arm. We report a case of ruptured tendon of the right biceps brachii in a 55-year-old male injured during pull-up exercise 2 years ago. Sonography demonstrated the presence of echoic material filling the bicipital groove. This material erroneously resembled the biceps tendon and resulted in a false first impression of intact tendon. However, a careful longitudinal scan failed to show the anisotropy and fibrillar pattern of the tendon. The bicipital groove was filled with amorphous fibrous scar tissue and the hypoechoic defect could only be detected in the area close to muscle-tendon junction. Magnetic resonance imaging demonstrated rupture of the long head tendon at the insertion of superior glenoid labrum and retraction distally. Physicians should be alert to this pitfall of using ultrasonography if the long head tendon has been ruptured for a long time.
