Background
Pyopneumothorax secondary to Streptococcus constellatus infection is a clinically rare event, and few cases have been reported.
Case presentation
We report the case of a 55-year-old Han Chinese man with underlying diabetes who presented with fever of 17 days duration. A pulmonary computed tomography scan revealed right-sided massive pyopneumothorax. A culture of the pleural effusion and blood grew S. constellatus. A drug sensitivity test showed that the isolate was sensitive to linezolid, penicillin G, cefotaxime, vancomycin, and cefuroxime. Our patient was treated with linezolid for a total of 6 weeks. Subsequently, his chest computed tomography scan showed improved lung condition.
Conclusion
To the best of our knowledge, this is the first case of pyopneumothorax secondary to S. constellatus to be treated with linezolid. Pyopneumothorax may be caused by streptococcal infection, and linezolid is another good choice for treatment.
