BACKGROUND Simultaneous infection in tuberculosis (TB) is rare. The mixed infection between Streptococcus anginosus group (SAG) and M. tuberculosis (MTB) has not been reported in children. The aim of this report was to describe a pediatric case with a pulmonary abscess caused by the duality SAG-MTB co-infection. CASE PRESENTATION An 11-year-old boy with an acute onset of throbbing pain of two-day evolution located in the anterior chest wall. The patient reported a history of fever, cough and rhinorrhea during the last seven days. An anterior chest radiography revealed a heterogenic opacity at the lower right lobe while the lateral projection showed an obliteration at the anterior diaphragmatic insertion. Parenteral Ceftriaxone (100 mg/kg/day) and Dicloxacillin (200 mg/kg/day) was started. The abscess was subsequently drained and analyzed. After a year of follow-up, the patient remained asymptomatic. CONCLUSION This case represents the first reported case of pulmonary co-infection involving MTB and SAG in an immunocompetent pediatric patient.

在具有免疫功能的小儿患者中与链球菌链球菌和结核分枝杆菌同时感染。病例报告。

背景技术结核病（TB）的同时感染很少见。尚未在儿童中报告过链球菌性心绞痛组（SAG）和结核分枝杆菌（MTB）之间的混合感染。本报告的目的是描述由双重性SAG-MTB共感染引起的肺脓肿的小儿病例。病例表述位于胸前壁的一名11岁男孩，在两天的时间内发生了剧烈的搏动性疼痛发作。该患者报告最近7天内有发烧，咳嗽和鼻漏的病史。前胸片显示右下叶不透明，侧面投影显示前diaphragm肌插入物消失。开始肠胃外头孢曲松（100 mg / kg /天）和双氯西林（200 mg / kg /天）。随后排空脓肿并进行分析。经过一年的随访，患者仍无症状。结论该病例代表了第一例报道的免疫功能患儿肺部合并感染，涉及MTB和SAG。
