中文摘要
背景： 化脓性肌炎是一种少见的骨骼肌细菌感染。A组链球菌（GAS）在儿科病例中所占比例较小，而颞肌受累极为罕见。
病例描述： 我们报告2例既往健康的儿童，一名7岁男孩和一名6岁女孩，表现为急性中耳炎（AOM）和疼痛性单侧颞下颌肿胀。计算机断层扫描显示AOM伴颞肌炎，第一例并发乳突炎。两例均接受静脉抗生素治疗，第一例需要引流和乳突切除术，并完全康复。两例均分离出GAS。
结论： 对于表现为AOM和疼痛性颞部肿胀的儿童，应考虑GAS颞肌化脓性肌炎。影像学对于诊断和评估疾病范围至关重要。手术治疗应个体化。
英文摘要
BACKGROUND: Pyomyositis is an uncommon bacterial infection of skeletal muscle. Group A Streptococcus (GAS) accounts for a smaller proportion of pediatric cases, and temporal muscle involvement is exceptionally rare.
CASE DESCRIPTION: We report 2 previously healthy children, a 7-year-old boy and a 6-year-old girl, who presented with acute otitis media (AOM) and painful unilateral temporomandibular swelling. Computed tomography revealed AOM with temporal myositis, complicated by mastoiditis in the first case. Both were treated with intravenous antibiotics, and the first case required drainage and mastoidectomy, with full recovery. GAS was isolated in both cases.
CONCLUSIONS: GAS temporal pyomyositis should be considered in children presenting with AOM and painful temporal swelling. Imaging is crucial for diagnosis and assessment of disease extent. Surgical management should be individualized.
