Key result
CT manifestations of H1N1 infection include consolidations, ground-glass opacities, interlobular septal thickening, and small nodules, requiring clinical correlation for definitive diagnosis.
Why the study?
What are the thoracic CT manifestations of swine-origin influenza A (H1N1) viral infection?
What are the thoracic CT manifestations of swine-origin influenza A (H1N1) viral infection?
Thoracic CT findings of H1N1 influenza include consolidations and ground-glass opacities, which must be correlated with clinical and laboratory results for definitive diagnosis.
Nonspecific CT features of H1N1 require clinical correlation; leaves open prospective differentiation from other viral pneumonias.
OBJECTIVE: The purpose of this article is to illustrate and describe various CT manifestations of swine-origin influenza A (H1N1) viral infection. CONCLUSION: The imaging findings seen in patients with H1N1 infection include consolidations, ground-glass opacities, interlobular septal thickening, small nodules, and findings suggestive of small airways disease, among others. Definitive diagnosis is based on correlation of the CT findings with the clinical symptoms and laboratory test results.

Marchiori et al. (2011) conducted a review in Swine-origin influenza A (H1N1) viral infection. CT imaging was evaluated on CT manifestations. CT manifestations of H1N1 infection include consolidations, ground-glass opacities, interlobular septal thickening, and small nodules, requiring clinical correlation for definitive diagnosis.
