原发性热带化脓性肌炎,通常由金黄色葡萄球菌引起,以骨骼肌化脓为特征,表现为单个或多个脓肿。另一种罕见的致病生物是流行地区的结核分枝杆菌。这里,我们报告了一例原发性结核性化脓性肌炎,表现为右膝化脓性关节炎和右大腿和胸壁多部位化脓性肌炎。一开始就忽视了结核性病因,导致诊断延迟.患者最初被诊断为,使用超声检查,MRI和没有结核病的全身症状,与细菌性化脓性肌炎和广谱抗生素治疗。然而,对膝关节抽吸物进行的进一步研究产生了阴性培养物和基于盒的核酸扩增测试阳性,which,伴随着他的症状无法解决,提示原发性结核性化脓性肌炎。通过切开和引流病灶并完成抗结核治疗,他成功地得到了治疗。
Primary tropical
pyomyositis, commonly caused by Staphylococcus aureus, is characterised by suppuration in skeletal muscles, which manifests as single or multiple abscesses. Another rare causative organism is Mycobacterium tuberculosis in endemic areas. Here, we report a case of primary tuberculous
pyomyositis presenting as septic arthritis of the right knee and multiple site
pyomyositis of the right thigh and chest wall. A tuberculous aetiology was overlooked at first, which resulted in a diagnostic delay. The patient was initially diagnosed, using ultrasonography, MRI and an absence of systemic symptoms of tuberculosis, with bacterial
pyomyositis and treated with broad-spectrum antibiotics. However, further investigations performed on knee joint aspirate yielded negative cultures and a positive cartridge-based nucleic acid amplification test, which, along with a non-resolution of his symptoms, suggested a primary tuberculous
pyomyositis. He was successfully managed with incision and drainage of the lesions and completion of anti-tubercular therapy.
