CT Findings in Pediatric Novel Influenza A (H1N1)-Associated Pneumonia.
OBJECTIVE
To explore CT findings in pediatric novel influenza A (H1N1)-associated pneumonia


METHODS
We examined the CT findings in a series of six children with influenza H1N1-associated pneumonia.


RESULTS
In this series of cases, the predominant CT patterns were consolidations surrounded by ground glass opacities (GGOs) as well as isolated GGOs in all patients. Atelectasis was present in the right upper lobe (n=2) in three cases and pneumomediastinum in two.


CONCLUSIONS
In this series of cases, there may be no imaging differences between pediatric and reported adult influenza H1N1 cases and other viral pneumonia cases even with CT. Pneumomediastinum and atelectasis, especially in the right upper lobe, may frequently present in influenza H1N1-associated pneumonia as well as in other pediatric respiratory diseases.
