The normal anatomy of the long head of the biceps tendon of the shoulder has been described in detail [1]. Descriptions of different pathologic processes affecting this structure also have been published [1-3] but have been incomplete, showing only a limited variety of abnormalities. In this article, abnormalities of the long head of the biceps tendon seen on MR images are illustrated in greater variety and detail. Recognizing abnormalities of the biceps tendon is important because they are a common source of shoulder pain both alone and in combination with abnormalities of the rotator cuff, labrum, and other structures. Because incomplete diagnosis can lead to treatment failure, it is important to recognize less common imaging manifestations of common entities.
肩部肱二头肌长头的正常解剖结构已得到详细描述[1]。关于影响该结构的不同病理过程的描述也已发表[1-3]，但并不完整，仅显示了有限的各种异常情况。在本文中，将更全面、详细地展示在磁共振成像（MR）图像上所见的肱二头肌长头异常情况。认识肱二头肌肌腱的异常很重要，因为它们无论是单独存在还是与肩袖、盂唇及其他结构的异常共同存在时，都是肩部疼痛的常见原因。由于诊断不完整可能导致治疗失败，识别常见疾病的不常见影像学表现很重要。
