Core Tip

Core Tip: This report describes a 2-year-old boy presenting with a lung abscess attributed to Streptococcus pseudopneumoniae (S. pseudopneumoniae) infection. Pulmonary abscess is uncommon in pediatric respiratory diseases, and can be caused by a variety of pathogens. Despite multiple etiological tests conducted upon admission, no pathogen was identified. Eventually, metagenomic next-generation sequencing (mNGS) of bronchoalveolar lavage fluid was employed and confirmed the presence of S. pseudopneumoniae. There are currently no reports of pulmonary abscess caused by S. pseudopneumoniae infection in the international literature. This case highlights the significance of mNGS in pulmonary infectious diseases, which is regarded as a complementary approach to conventional respiratory pathogen diagnostic techniques.
