A 41-year-old male patient was admitted following a hypoxic cardiac arrest with a tooth aspiration in the right lower lobe, which was removed using a rigid bronchoscope. Despite appropriate antibiotic treatment for pneumonia, the patient developed a sepsis. Point-of-care ultrasound (POCUS) revealed a lung abscess (LA) associated to a pleural empyema (PE). On parasagittal section (Fig. 1 A), lung ultrasound showed a right lower lobe abscess appearing as a rounded anechoic image above the diaphragm, with suspended microbubbles (air content). Condensed lung parenchyma (CL) was observed around the structure. Behind it was another collection with smooth margins, a lenticular wall attached to the pleura, which appeared to be pleural empyema. The association of a LA with PE suggested the existence of bronchopleural fistula. A subsequent chest computed tomography scan confirmed this diagnosis, with transverse (B) and parasagittal (C) sections (Fig. 1).
