A 34-year-old female recreational badminton player presented with left ankle pain 1 week after a recreational badminton game. She reported experiencing a similar pattern of pain in her right ankle 4 months before that had persisted for 3 months. On plain radiography, callus formation was evident on the right distal fibula, and a subtle lesion was observed on the left side. Ultrasound was performed with the clinical suspicion of bilateral, nonsimultaneous, distal fibular stress fracture. Focal hyperechoic thickening of the periosteum with irregularity and hypoechoic periosteal edema over the left distal fibula were identified. These findings were consistent with stress fracture, and an early phase of distal fibular stress fracture was diagnosed. This case report highlights that ultrasound can be an alternative modality to magnetic resonance imaging or bone scan scintigraphy for the early diagnosis of stress fracture.
一位 34 岁的女性业余羽毛球运动员，在一场业余羽毛球比赛后一周出现左踝关节疼痛。她报告说，4 个月前她的右脚踝也出现过类似的疼痛模式，持续了 3 个月。在普通 X 光片上，右侧腓骨远端有骨痂形成，左侧可见细微病变。临床怀疑双侧、非同时性、腓骨远端应力性骨折，行超声检查。左侧腓骨远端骨膜呈局限性高回声增厚，不规则，骨膜下低回声水肿。这些发现符合应力性骨折的特征，诊断为腓骨远端应力性骨折早期。本病例报告强调，超声检查可作为磁共振成像或骨扫描闪烁成像的替代方法，用于早期诊断应力性骨折。
