A 20-year-old white man presented with a localized unilateral swelling in the popliteal fossa. Ultrasound (US) showed the presence of an accessory muscle, the tensor fasciae suralis. The muscle was located in the proximal portion of the popliteal fossa, superficial to the medial head of the gastrocnemius. Its long tendon extended inferiorly to join the Achilles tendon. Magnetic resonance images correlated well with the US findings, confirming the diagnosis. Tensor fasciae suralis muscle is a rare cause of popliteal swelling and must be differentiated from other masses. Both US and magnetic resonance imaging can diagnose it but we suggest US as the first-line technique in its evaluation.
一名20岁白人男性因腘窝局限性单侧肿胀前来就诊。超声检查显示存在一块副肌，即腓肠肌筋膜张肌。该肌肉位于腘窝近端，在腓肠肌内侧头的浅面。其长肌腱向下延伸与跟腱相连。磁共振成像与超声检查结果相关性良好，确诊了该病症。腓肠肌筋膜张肌是腘窝肿胀的罕见原因，必须与其他肿块相鉴别。超声和磁共振成像均可对其进行诊断，但我们建议将超声作为评估该病的一线技术。
