Isolated Pectoralis Minor Tendon Rupture with Subclavian Vein Thrombosis

Isolated insertional ruptures of the pectoralis minor tendon at the coracoid process are a rare condition. Hitherto, very few cases have been reported in the literature. A precise diagnosis is often difficult to obtain and commonly requires advanced imaging to confirm the suspicion and rule out concomitant injuries. All cases reported in the literature to date have been treated conservatively, with excellent results and no further complications. Here, however, we present the case of a patient who had developed a subclavian vein thrombosis. Furthermore, we provide an overview over and draw comparisons to the cases described in the literature. Despite the effectiveness of the conservative treatment, physicians should be aware that adverse events may occur.
