摘要

Subperiosteal abscess is a recognized complication of pediatric acute osteomyelitis and has traditionally been managed with surgical drainage. Evidence supporting minimally invasive ultrasound-guided therapeutic alternatives in children remains limited. We report three pediatric cases of acute osteomyelitis complicated by subperiosteal abscesses successfully treated with ultrasound-guided percutaneous aspiration. In all patients, ultrasound demonstrated subperiosteal collections measuring 4–7 mm in thickness, with no evidence of substantial intraosseous abscess on ultrasound or magnetic resonance imaging. Percutaneous aspiration was performed under real-time ultrasound guidance using fine-caliber needles, without indwelling catheter placement. Purulent material was obtained in all cases, with cultures positive for methicillin-sensitive Staphylococcus aureus. All patients showed rapid clinical and laboratory improvement within 24–48 h, without procedure-related complications, recurrence during follow-up, or subsequent need for surgical drainage. These cases illustrate the feasibility and potential clinical value of ultrasound-guided percutaneous aspiration as a minimally invasive therapeutic option in carefully selected pediatric patients with isolated subperiosteal abscesses.
