We report two cases and review the characteristics of pyomyositis. The courses of patients who presented with pyomyositis at the Maricopa Medical Center (Phoenix) are detailed. Ninety-eight reported cases over the last 20 years in North America, found through a MEDLINE search, are summarized. Infection with the human immunodeficiency virus (HIV) may predispose the patient to pyomyositis. The onset is usually insidious with progression to large purulent collections and significant morbidity. The diagnosis is frequently suggested by findings of imaging studies. Staphylococcus aureus is responsible for most cases in tropical areas but is less frequently associated with cases in North America. Since infection with HIV predisposes patients to bacterial infections, pyomyositis will occur more frequently in this patient population. Increased awareness of the disease will improve management. Following aspiration or surgical drainage, therapy with broad-spectrum empirical antibiotics may be considered initially in the treatment of pyomyositis.
我们报告了两例病例，并回顾了脓性肌炎的特征。详细介绍了在马里科帕医疗中心（凤凰城）出现脓性肌炎的患者病程。通过医学文献数据库检索，总结了过去20年在北美报道的98例病例。感染人类免疫缺陷病毒（HIV）可能使患者易患脓性肌炎。起病通常隐匿，进展为大的脓性积液并伴有严重的发病率。影像学检查结果常提示诊断。金黄色葡萄球菌是热带地区大多数病例的病因，但在北美与病例的关联较少。由于感染HIV使患者易患细菌感染，脓性肌炎在该患者群体中会更频繁地发生。提高对该疾病的认识将改善治疗。在穿刺抽吸或手术引流后，治疗脓性肌炎最初可考虑使用广谱经验性抗生素。
