Pyomyositis is an uncommon infection in temperate climates, usually resulting from Staphylococcus aureus infection of skeletal muscle. In this report, the authors describe a patient with untreated Type 2 diabetes mellitus who suffered nonpenetrating blunt trauma to his left anterior thigh, and S. aureus pyomyositis and secondary osteomyelitis of his proximal tibia and patella subsequently developed as a result of delayed diagnosis and treatment. Patients with diabetes mellitus are at increased risk for the development of pyomyositis because of more frequent S. aureus colonization of skin, nasal mucosa, and oropharynx; a delay in definitive treatment can lead to significant morbidity in these patients. Computed tomography or magnetic resonance imaging may be helpful in the diagnosis of pyomyositis. An anemia of chronic disease may result from this disorder, which resolves with treatment.
脓性肌炎在温带气候地区是一种不常见的感染，通常由金黄色葡萄球菌感染骨骼肌引起。在本报告中，作者描述了一名患有未经治疗的2型糖尿病患者，其左大腿前部遭受非穿透性钝器伤，随后因诊断和治疗延迟而发展为金黄色葡萄球菌脓性肌炎以及近端胫骨和髌骨的继发性骨髓炎。糖尿病患者发生脓性肌炎的风险增加，因为皮肤、鼻粘膜和口咽部金黄色葡萄球菌定植更为频繁；明确治疗的延迟可导致这些患者出现严重的发病率。计算机断层扫描或磁共振成像可能有助于脓性肌炎的诊断。这种疾病可能导致慢性病性贫血，治疗后可缓解。
