The peroneus quartus (PQ) muscle is a rare but sometimes missed potential etiology of ankle pain and tendon subluxation. We report the case of a 16-year-old boy who presented with lateral right ankle pain and subluxation of peroneal tendons. He had a history of non-Hodgkin lymphoma and palpable distal fibular osteochondroma. Seven months after excision of the exostosis and repair of the peroneal tendon retinaculum, the pain recurred. Imaging showed a split peroneus brevis (PB) tendon. During surgery, a PQ muscle was found and excised, and the PB tendon was repaired. One year after surgery, the patient's symptoms were resolved.
第四腓骨肌（PQ）是一种罕见但有时会被漏诊的踝关节疼痛和肌腱半脱位的潜在病因。我们报告一例16岁男孩，其表现为右踝关节外侧疼痛和腓骨肌腱半脱位。他有非霍奇金淋巴瘤病史，可触及远端腓骨骨软骨瘤。外生骨疣切除及腓骨肌腱支持带修复7个月后，疼痛复发。影像学检查显示腓骨短肌（PB）肌腱断裂。手术中发现并切除了一条PQ肌，修复了PB肌腱。术后1年，患者症状消失。
