From: Demystifying the persistent pneumothorax: role of imaging
A 56-year-old male presented to the ED with right-sided chest pain. Frontal chest radiograph (a) demonstrated a large right hydro pneumothorax, which did not completely resolve after chest tube placement (b). Coronal (c) and axial (d) CT images demonstrated a cavitating cancer within the right upper lung with an associated alveolopleural fistula (arrow). In addition, right paratracheal lymphadenopathy is seen. Extensive alveolar opacities in the re-expanded lung are consistent with pneumonia and reexpansion edema
