Neonatal methicillin-resistant Staphylococcus aureus pneumonia–related recurrent fatal pyopneumothorax: A case report and review of literature

Figure 1 Chest radiographs one day before admission and on the first day of hospitalization. A: High-density shadows in the right upper lung and left lower lung (one day before admission); B: Right pneumothorax (approximately 90% compression) with a blunt right costophrenic angle, blurring in the left lung, and a disappeared left costophrenic angle (on admission); C: High-density shadows in the right lung and left lower lung, with right pneumothorax, and blurred left diaphragm and costophrenic angle (after drainage of the right pleural cavity on the first day of hospitalization).

Figure 2 Chest radiographs on the third and fourth days of hospitalization. A: High-density shadows in the right upper lung and left lower lung, with blurred left diaphragm and costophrenic angle (on the third day of hospitalization, DOH 3); B: High-density shadows in the right upper lung and left lower lung, with blurred left diaphragm, costophrenic angle, and right pneumothorax (on DOH 4).

Figure 3 Chest radiographs on the fifth day of hospitalization. A: Bilateral pneumothorax (nearly 100% compression of the left lung) with right lung consolidation (before cardiac arrest on the morning of the fifth day of hospitalization, DOH 5); B: Obvious recruitment of the left lung (after drainage of the left pleural cavity and successful resuscitation on DOH 5); C: Bilateral pneumothorax was more obvious than that in Figure 3B (at night on DOH 5).

Figure 4 Chest radiographs on the sixth, seventh, eighth, ninth, and eleventh days of hospitalization. A: Recurrent bilateral pyopneumothorax, with multiple high-density shadows and pneumatoceles (orange arrows) in both lungs (on the sixth day of hospitalization, DOH 6); B: Recurrent bilateral pyopneumothorax, with multiple high-density shadows and pneumatoceles (orange arrows) in both lungs (on DOH 7); C: Multiple pneumatoceles (orange arrows) in the right lung and high-density shadows in both lungs (on DOH 8); D: Multiple high-density shadows and pneumatoceles (orange arrows) in both lungs (on DOH 9); E: Recurrent pyopneumothorax and pneumatocele (orange arrow) in the right lung and high-density shadows in both lungs (on DOH 11).
