Since the availability of magnetic resonance imaging (MRI), the suspected diagnosis of an accessory muscle of the lower extremity can now be confirmed without the need for invasive procedures. The accessory soleus, peroneus quartus, and flexor digitorum longus accessorius are anomalous muscles of the lower extremity that can be diagnosed by MRI. These accessory muscles are probably more common than once thought and can now be easily distinguished from other space occupying lesions that can occur around the ankle. MRI of these anomalous muscles enables one to make a definitive diagnosis without a biopsy. In those symptomatic patients, the origins and insertions of these accessory muscles can be accurately evaluated by MRI prior to any anticipated surgical intervention.
自从磁共振成像（MRI）问世以来，现在无需进行侵入性检查即可确诊下肢副肌。比目鱼肌副肌、第四腓骨肌和副趾长屈肌是下肢的异常肌肉，可通过MRI诊断。这些副肌可能比以往认为的更为常见，现在可以很容易地与踝关节周围可能出现的其他占位性病变区分开来。对这些异常肌肉进行MRI检查可在无需活检的情况下做出明确诊断。对于有症状的患者，在任何预期的手术干预之前，通过MRI可以准确评估这些副肌的起止点。
