- initial radiograph was abnormal in 28 of the 66 patients (42%)
- with patchy consolidation in 14 out of these 28 (50%)
- ground-glass opacities in 7 out of 28 (25%), and
- ground-glass opacities mixed with consolidation in 7 (25%)
- the abnormalities were bilateral in 20 of the 28 patients (71%)
- located in the lower lung zones in 20 (71%), and
- diffuse in 7 (25%).
In short, these results suggest that H1N1-associated chest x-ray abnormalities tend to be dependent (i.e., in the lower lungs) and patchy consolidation, often bilateral, was the most common finding chest X-ray finding. Nevertheless, much of its mechanism remain unknown pending further larger studies.
