Pyomyositis is a group of infectious diseases involving muscle tissue. Staphylococcus aureus is usually the causal agent. Group A Streptococcus infections are uncommonly isolated in pyomyositis. Streptococcal pyomyositis can be distinguished by its severity. Death rate may be as high as 50%.
Diagnosis of cervical pyomyositis was made in 2 patients on the basis of ultrasound and computerized tomography findings. Group A Streptococcus was isolated from local samples. The diagnosis was confirmed at surgery. Host defense mechanisms were not deficient in either patient. Outcome was favorable in both patients after antibiotic therapy.
Because of the seventy of group A streptococcal pyomyositis, early diagnosis is essential for prognosis. Ultrasound and computerized tomography are very helpful. Group A streptococcal pyomyositis should be considered as a life-threatening disease.
脓性肌炎是一组累及肌肉组织的感染性疾病。金黄色葡萄球菌通常是病原体。A 组链球菌感染在脓性肌炎中较少分离出来。链球菌性脓性肌炎可因其严重程度而有所区别。死亡率可能高达 50%。
根据超声和计算机断层扫描结果，2 例患者被诊断为颈部脓性肌炎。从局部样本中分离出 A 组链球菌。手术确诊。两名患者的宿主防御机制均无缺陷。抗生素治疗后两名患者的预后均良好。
由于 A 组链球菌性脓性肌炎病情严重，早期诊断对预后至关重要。超声和计算机断层扫描非常有帮助。A 组链球菌性脓性肌炎应被视为一种危及生命的疾病。
