Patchy consolidation, often bilateral, was the most common finding.
Clinically, 2009 pandemic influenza A (H1N1) virus infection is more likely than typical seasonal influenza to cause severe disease and pneumonia in young people. These authors reviewed chest radiography findings in 66 patients (mean age, 27 years; age range, 9 months to 60 years) who underwent imaging as part of the clinical work-up for suspected influenza A (H1N1) virus infection at a hospital in Michigan from May to July 2009.
Overall, 25 patients (38%) had confirmed H1N1 infection. The initial radiograph was abnormal in 28 of the 66 patients (42%), with patchy consolidation in 14 (50%), ground-glass opacities in 7 (25%), and ground-glass opacities mixed with consolidation in 7 (25%). Abnormalities were bilateral in 20 of the 28 patients …
