This study was conducted to evaluate early diagnosis, clinical course, and treatment outcome in children with pyomyositis.
Between 2001 and 2006, 6 children with a mean age of 7.2 years were diagnosed and treated for pyomyositis in our clinic. The most common site of involvement was the hip and thigh region. All patients underwent early magnetic resonance imaging (MRI) examination that played a significant role in the early diagnosis and management of the disease.
Staphylococcus aureus was the most common pathogen and was identified in 3 cases. Intravenous antibiotics were administered and were followed by oral agents for an additional period. The duration of therapy ranged from 3 to 6 weeks. No surgical intervention was needed. Magnetic resonance imaging was used to evaluate response to the therapy.
Although pyomyositis is a rare disease, it should be considered in the differential diagnosis of immediate onset of musculoskeletal pain in children. Early diagnosis and antibiotic treatment are important as major complications such as abscess formation and sepsis can be avoided. Having a high sensitivity to reactive inflammatory changes, MRI is a valuable tool in the armamentarium of the clinician in early diagnosis of pyomyositis.
本研究旨在评估儿童肌炎的早期诊断、临床过程和治疗结果。
2001 年至 2006 年间，我们诊所诊断并治疗了 6 例平均年龄为 7.2 岁的儿童肌炎患者。最常见的受累部位是臀部和大腿区域。所有患者均进行了早期磁共振成像（MRI）检查，这对疾病的早期诊断和治疗起了重要作用。
金黄色葡萄球菌是最常见的病原体，在 3 例中得到了鉴定。静脉内给予抗生素，并在后续口服药物治疗。治疗时间从 3 周到 6 周不等。无需手术干预。磁共振成像用于评估对治疗的反应。
虽然肌炎是一种罕见疾病，但在儿童急性发作的肌肉骨骼疼痛的鉴别诊断中应考虑到它。早期诊断和抗生素治疗很重要，因为可以避免脓肿形成和败血症等主要并发症。具有高敏感性的反应性炎症变化，MRI 是临床医生早期诊断肌炎的有价值的工具。
