RESUMO
Primary pyomyositis is an acute bacterial infection of skeletal muscle leading to single or multiple abscess formation. The etiologic agent most frequently identified is Staphylococcus aureus, principal emerging pathogen of invasive musculoskeletal infections in otherwise healthy children. It is important to maintain a high level of suspicion, since early diagnosis and effective empirical treatment may prevent progression to a more severe disease. We present a case of bilateral thigh pyomyositis caused by community-acquired methicillin-resistant Staphylococcus aureus in an otherwise healthy eight-year-old child.

La piomiositis es una infección bacteriana aguda del músculo esquelético que resulta en abscesos localizados, únicos o múltiples. El agente etiológico más frecuente es el Staphylococcus aureus, principal patógeno emergente de infecciones invasivas del músculo esquelético en pacientes pediátricos previamente sanos. Es importante el alto índice de sospecha, ya que el diagnóstico precoz y el tratamiento empírico eficaz permiten evitar la progresión hacia un cuadro de mayor gravedad. Presentamos el caso de un niño de 8 años de edad, previamente sano, con piomiositis de muslo bilateral por Staphylococcus aureus meticilino resistente de la comunidad.
