Background: Aspiration pneumonia in patients in immunocompetent populations is rare, and secondary pyothorax due to puncture operations during treatment has been reported rarely.
Methods: We report a confirmed case of aspiration pneumonia caused by Prevotella. The pathogen was detected and confirmed using percutaneous lung puncture and high-throughput next-generation sequencing (NGS).
Results: The patient developed secondary pyothorax, severe rash, and exacerbation of symptoms following the lung puncture. Finally, after adjusting the antibiotic regimen and performing chest drainage and washout, the patient's lesions were absorbed, symptoms improved, and the rash disappeared.
Conclusions: Prevotella aspiration pneumonia can occur in immunocompetent individuals, and invasive bronchoscopic alveolar lavage may be considered as an option to reduce the risk of infectious organism translocation.
