“…On the other hand, Marchiori et al 5 reported that fatal cases of influenza A (H1N1) pneumonia present as areas of consolidation with or without GGO on CT scans (AIP pattern on CT scans), and the abnormalities are pathologically correlated with diffuse alveolar damage. 5 Furthermore, Grieser et al 16 reported that the CT scores calculated by multiplying the lesion pattern grades (1, normal; 2, GGO; and 3, consolidation) by the extent of lung lesion (to the nearest 10% of lung volume involved) in acute respiratory distress syndrome caused by influenza A (H1N1) pneumonia have a prognostic value in the prediction of mortality. Therefore, it seems that pattern and extent of lung lesions observed at CT may be a determining factor for predicting patient clinical course and prognosis.…”

“…A separate group has confirmed the utility of HRCT obtained during the acute phase of pathologically confirmed diffuse alveolar damage, and found that increased radiological lung involvement, as well as traction bronchiectasis, were associated with death [80]. Finally, published studies of the 2009 H1N1 epidemic indicate that HRCT is similarly useful in predicting mortality and long-term morbidity in patients with ARDS from influenza A [69, 81]. Our group’s recent observations complement and add to these investigations and suggest that HRCT performed early in the course of ARDS may prognosticate functional impairment in survivors months after discharge [18].…”

“…Chung and colleagues [98], exploring the extension of lung abnormalities in the early phase of ARDS, found that non-survivors presented a higher amount of lung involvement without any differences in consolidation and ground area opacity extensions. Similarly, in severe ARDS due to H1N1 infection, non-survivors had a significantly higher CT score (computed from the extension and type of lung abnormalities) compared to survivors, with an optimal cutoff of 100 to predict short-term mortality [99]. …”
