Abstract

Background: Lung abscess found on chest X-ray and computed tomography examinations is rare in infants and young children. Several pathogens can cause lung abscesses, with the most common pathogens being anaerobes, Streptococci and Staphylococcus aureus. Streptococcus pseudopneumoniae (S. pseudopneumoniae) is a member of the Streptococcaceae family, and is mainly isolated from respiratory tract specimens. There are currently no cases of lung abscess caused by S. pseudopneumoniae in the literature.

Case summary: A 2-year-old boy was admitted to hospital due to persistent cough and fever. Lung computed tomography examination suggested the formation of a lung abscess. His diagnosis was not confirmed by testing for serum respiratory pathogens (6 items), respiratory pathogen nucleic acid (27 items), and laboratory culture. Finally, metagenomic next-generation sequencing of bronchoalveolar lavage fluid revealed the presence of S. pseudopneumoniae, confirming its role in causing the lung abscess. After receiving antibiotic treatment, reexamination with lung computed tomography showed that the abscess was resorbed and the patient's outcome was good.

Conclusion: This is the first report of a lung abscess in a child caused by S. pseudopneumoniae infection. Metagenomic next-generation sequencing of bronchoalveolar lavage fluid is helpful in achieving rapid and accurate pathogen identification.

儿童假肺炎链球菌引起的肺脓肿:病例报告和文献综述。
背景:胸部 X 光和计算机断层扫描检查发现的肺脓肿在婴幼儿中很少见。多种病原体可导致肺脓肿,最常见的病原体是厌氧菌、链球菌和金黄色葡萄球菌。假肺炎链球菌(S. pseudopneumoniae)属于链球菌科,主要从呼吸道标本中分离出来。病例摘要:一名两岁男孩因持续咳嗽和发烧入院。肺部计算机断层扫描检查显示有肺脓肿形成。通过检测血清呼吸道病原体(6 项)、呼吸道病原体核酸(27 项)和实验室培养,均未确诊。最后,支气管肺泡灌洗液的元基因组下一代测序发现了假肺炎双球菌,证实了它是导致肺脓肿的罪魁祸首。接受抗生素治疗后,肺部计算机断层扫描复查显示脓肿已吸收,患者预后良好:这是首例由假肺炎双球菌感染导致儿童肺脓肿的报告。支气管肺泡灌洗液的元基因组下一代测序有助于快速准确地鉴定病原体。
