A female infant was born by vaginal delivery at 39 weeks' gestation. The Apgar score was 7 at 1 minute and 9 at 5 minutes. Birth weight was 2630 g. She developed a mild, self-resolving tachypnea with normal oxygen saturation values. Radiography showed a normal right lung and an opacified left hemithorax (Figure). No additional abnormalities were found.
