Abstract：
BACKGROUND: Symptomatic muscle hernias are not uncommon in the lower extremities and are a rare cause of chronic leg pain. They are most commonly seen in the tibialis anterior muscle, occurring through fascial defects, usually after trauma. There are about 200 cases of muscle hernias described in the literature. The diagnosis is challenging as most of the patients present with non-specific chronic leg pain. Dynamic muscle ultrasonography at rest and at stress is often used for the diagnosis.
METHODS: We describe a case of tibialis anterior muscle hernia presenting with persistent dull pain and swelling along the anterior aspect of the leg on straining the leg muscles. Dynamic ultrasonography was performed, which showed a defect in the fascial sheath of the muscle through which the tibialis anterior muscle herniated and produced a focal bulge along the anterior aspect of the leg. Based upon physical examination and dynamic ultrasonographic findings, a diagnosis of tibialis anterior muscle hernia was made.
CONCLUSIONS: Tibialis anterior muscle hernia is a rare diagnosis and should be included in the differential diagnosis in a patient with chronic leg pain and swelling. Dynamic ultrasound is crucial in confirming the diagnosis and should be done on straining the muscles of the affected limb.

摘要：
背景：症状性肌肉疝在下肢并不少见，是慢性腿部疼痛的罕见原因。它们最常见于胫骨前肌，通过筋膜缺损发生，通常在创伤后。文献中描述了大约200例肌肉疝。由于大多数患者存在非特异性慢性腿痛，因此诊断具有挑战性。静息和压力下的动态肌肉超声检查通常用于诊断。
方法：我们描述了一例胫骨前肌疝，表现为腿部肌肉紧张时腿部前部持续的迟钝疼痛和肿胀。进行动态超声检查，显示出肌肉筋膜鞘的缺损，胫骨前肌通过筋膜鞘突出，并沿腿部前部产生局灶性凸起。根据体格检查和动态超声检查结果，诊断为胫骨前肌疝。
结论：胫骨前肌疝是一种罕见的诊断，应纳入慢性腿部疼痛和肿胀患者的鉴别诊断中。动态超声在确认诊断方面至关重要，应在使受影响肢体的肌肉紧张时进行。
