A 6-month-old girl was brought to the ED with fever, cough, and irritability; she appeared well-hydrated. She was born prematurely and had a long, complicated stay in NICU, where she received CPR on 2 occasions. There was concern about lung "congestion." The ED physician made a diagnosis of pneumonia. Rib fractures were also noted, but there was no history of fractures at the time of discharge from the NICU.
