Here, we report on a 75-year-old man with history of end-stage renal disease presenting after a syncopal event with lactic acidosis, leukocytosis, and mild hyper-bilirubinemia. Chest imaging revealed a loculated, left-sided pleural effusion; diagnostic thoracentesis identified Clostridia perfringens, consistent with an empyema. Video-assisted thoracic left lung decortication was performed; tissue culture also speciated Clostridia perfringens. Further imaging revealed concomitant acute cholecystitis, suggesting hematogenous seeding or transdiaphragmatic extension of Clostridia perfringens to pleural space from an abdominal source. The patient was successfully managed with laparoscopic cholecystectomy and discharged on a one-month course of amoxicillin-sulbactam. This case highlights the potential for Clostridia perfringens to produce a pleuropulmonary infection, necessitating timely diagnosis and intervention, to improve patient outcomes.
