Abstract：
Pyomyositis is an uncommon primary infection of skeletal muscle resulting in muscle inflammation followed by pus formation. Pyomyositis is typically caused by Staphylococcus aureus (S. aureus), and most cases are associated with skin penetration and/or immunosuppressive conditions in tropical or even temperate climates. We report a previously healthy, immunocompetent 44-year-old man who presented with fever and right lower back pain. He had received an analgesic injection for his back pain 12 days prior to this visit. His clinical course was further complicated by the coexistence of multiple muscular abscesses, renal infarction, and septic arthritis of the right shoulder. He underwent computed tomography-guided drainage of the abscess. The abscess and blood cultures were positive for methicillin-susceptible S. aureus. The patient responded well to prolonged treatment with cefazolin and cephalexin and was discharged 12 weeks after initial admission.
摘要：
化脓性肌炎是一种罕见的原发性骨骼肌感染，导致肌肉炎症，然后形成脓液。化脓性肌炎通常由金黄色葡萄球菌引起(S.金黄色葡萄球菌)，并且大多数病例与热带或甚至温带气候中的皮肤渗透和/或免疫抑制状况有关。我们报告了一个以前健康的，有免疫能力的44岁男子，发烧和右下背部疼痛。在这次访问之前的12天，他已经接受了止痛剂注射治疗。他的临床过程因多个肌肉脓肿的共存而进一步复杂化，肾梗死,和右肩的化脓性关节炎.他接受了计算机断层扫描引导的脓肿引流。脓肿和血培养对甲氧西林敏感的金黄色葡萄球菌呈阳性。患者对头孢唑啉和头孢氨苄的长期治疗反应良好，首次入院后12周出院。
