We describe the case of a 3-year-old boy who presented with limited flexion in the left knee. High-resolution magnetic resonance imaging allowed visualization of a fibrotic muscle band in the anatomic position of the fifth component of the quadriceps muscle, which was confirmed by surgical findings. After surgical resection, the patient achieved full recovery of range of motion of the knee.
To our knowledge, this is the first reported case of a fibrotic muscle band in the anatomic position of a previously described fifth accessory component of the quadriceps muscle that caused limited knee flexion in a child.
我们描述了一名3岁男孩的病例，该男孩左膝屈曲受限。高分辨率磁共振成像显示股四头肌第五个组成部分解剖位置处有一条纤维化肌束，手术结果证实了这一点。手术切除后，患者膝关节活动范围完全恢复。
据我们所知，这是首例报道的位于先前描述的股四头肌第五个附属组成部分解剖位置的纤维化肌束导致儿童膝关节屈曲受限的病例。
