We report a case of a 56-year-old man who sustained a ruptured long head of biceps tendon (LHBT) that presented with symptoms typical of a pectoralis major rupture. Magnetic resonance imaging revealed an isolated LHBT tear. Intraoperatively, the biceps tendon had an unusually thick distal segment entrapped under the insertion of the pectoralis major. Surgery led to an excellent outcome.
A ruptured LHBT with an associated large distal segment producing a mass effect on the pectoralis major can mimic a pectoralis major rupture and may ultimately require surgery to alleviate symptoms.
我们报告了一例 56 岁男性患者，其发生了肱二头肌长头肌腱（LHBT）断裂，表现出类似于胸大肌断裂的典型症状。磁共振成像显示 LHBT 撕裂。术中发现，肱二头肌肌腱的远端异常增厚段被夹在胸大肌的止点下。手术取得了极佳的效果。
伴有大的远端段的 LHBT 断裂并对胸大肌产生肿块效应可模拟胸大肌断裂，最终可能需要手术缓解症状。
