Abstract：
Pyomyositis is a bacterial infection of skeletal muscle leading to abscess formation. Younger males are predominantly involved, but pyomyositis may occur in all ages and sexes. Underlying systemic disease or accompanying immunocompromised states may increase the risk of pyomyositis. This is a report of a 72-year-old, male, with uncontrolled diabetes mellitus, presenting initially as a case of orbital cellulitis. Magnetic resonance imaging confirmed the presence of an abscess in the left lateral rectus. Antibiotic therapy was promptly initiated, and drainage of the abscess was performed via a transconjunctival approach. Pyomyositis resolved post-surgery and medical therapy. Residual exotropia was noted at the eighth month of follow-up necessitating subsequent strabismus surgery. Nine months post-treatment, left lateral rectus pyomyositis did not recur.
摘要：
化脓性肌炎是导致脓肿形成的骨骼肌的细菌感染。主要涉及年轻男性，但是化脓性肌炎可能发生在所有年龄和性别。潜在的全身性疾病或伴随的免疫受损状态可能会增加化脓性肌炎的风险。这是一个72岁老人的报告,男性,患有不受控制的糖尿病，最初表现为眼眶蜂窝织炎。磁共振成像证实左外侧直肌存在脓肿。抗生素治疗迅速开始，脓肿的引流是通过经结膜入路进行的。化脓性肌炎在手术和药物治疗后缓解。在随访的第八个月发现了残留的外斜视，需要进行后续的斜视手术。治疗后9个月,左直肌炎未复发。
