Accessory muscles are easily overlooked during imaging evaluation. Although usually discovered incidentally, they are occasionally symptomatic. With increasing utilization of cross-sectional imaging, the radiologist should be prepared to readily identify these anomalous muscles. It is particularly important to distinguish these anatomical variants from soft-tissue tumors prior to invasive intervention, reserving biopsy and surgery for children who are symptomatic. This report discusses a case of a flexor digitorum superficialis indicis muscle, an extremely rare but well-described accessory muscle, presenting as a painful mass in a 15-year-old girl. The report includes the clinical presentation, radiologic findings, and the significance to management.
在影像学评估过程中，副肌很容易被忽视。尽管它们通常是偶然发现的，但偶尔也会出现症状。随着横断面成像技术的使用日益增加，放射科医生应做好准备，以便能够轻松识别这些异常肌肉。在进行侵入性干预之前，将这些解剖变异与软组织肿瘤区分开来尤为重要，对于有症状的儿童，应保留活检和手术手段。本报告讨论了一例示指浅屈肌病例，这是一种极其罕见但已有充分描述的副肌，表现为一名15岁女孩的疼痛性肿块。该报告包括临床表现、影像学检查结果以及对治疗的意义。
