The biceps brachii muscle is prone to variants but absence of the long head of the biceps (LHB) tendon is an exceptionally rare anomaly. This report concerns the fourth case of bilateral congenital absence of the LHB tendon and presents the ultrasonography (US) and magnetic resonance (MR) findings. Our case has the peculiarity of being the first in which bilateral LHB tendon agenesis is not associated with rotator cuff or labral tears.
肱二头肌容易出现变异,但肱二头肌长头(LHB)肌腱缺如是一种极为罕见的异常情况。本报告涉及第四例双侧先天性LHB肌腱缺如病例,并展示了超声检查(US)和磁共振成像(MR)的结果。我们的病例具有独特性,是首例双侧LHB肌腱发育不全与肩袖或盂唇撕裂无关的病例。
