Abstract：
Anomalous muscle causes thoracic outlet syndrome (TOS). A 40-year-old man presented with numbness of the left upper extremity, similar to cervical spondylotic radiculopathy. He presented with a positive Bakody\'s test. However, magnetic resonance imaging showed no significant changes in the cervical spine and revealed an anomalous muscle adjacent to the left brachial plexus. We diagnosed the muscle as the cause of TOS and performed a resection, which resulted in symptomatic improvement.

异常肌肉引起胸廓出口综合征（TOS）。一名40岁的男子表现为左上肢麻木，类似于神经根型颈椎病。他提出了一个积极的Bakody测试。然而,磁共振成像显示颈椎无明显变化，并显示左臂丛神经附近有异常肌肉。我们诊断出肌肉是TOS的原因并进行了切除术，导致症状改善。
