In CT, the most common reported change in Influenza A(H1N1) was ground glass shadowing. Other changes recorded on CT were focal or multifocal consolidation, interstitial changes and pulmonary embolism [4, 13, 14] . CT was valuable in detecting positive findings in the presence of normal CXRs and showed more extensive pattern of involvement when compared to CXR [14] . These findings were similar to the authors' series although they did not find any evidence of pulmonary embolism in their sample population.
