Figure 1. Patient 1. P aeruginosa pneumonia in a 60-year-old man with cough, fever, and dyspnea at presentation 26 months after right single-lung transplantation for emphysema. Transverse chest CT scan (10-mm collimation, lung window) shows severe emphysema in the native left lung and peripheral homogeneous opacity in the left lower lobe (arrows). Peribronchial opacities in the right lower lobe were unchanged from those seen at CT 2 months previously. Cultures of bronchoalveolar lavage fluid from the left lower lobe grew P aeruginosa bacteria. The patient subsequently died of respiratory failure.
