Abstract
PURPOSE:
The aim of this study was to review the chest computed tomography (CT) findings in children with swine-origin influenza (H1N1) virus (S-OIV) infection.
MATERIALS AND METHODS:
The radiologists retrospectively reviewed chest CT findings in 12 children with S-OIV infection and recorded the following findings: ground-glass opacities (GGO), consolidation, nodules, reticular opacities, peribronchial cuffing, and air trapping; distribution; affected lobes. The presence of pleural effusions, pneumomediastinum, pulmonary interstitial emphysema (PIE), and lymphadenopathy was also recorded.
RESULTS:
Chest CT revealed GGO (67%), consolidation (67%), nodules (25%), peribronchial cuffing (42%), and air trapping (33%). The distribution of the lesions was random (75%), peribronchial (17%), or subpleural (8%). The lobes affected were the lower (92%), upper (58%), and middle (17%) lobes. There were associated pleural effusions (42%), PIE (42%), pneumomediastinum (33%), and lymphadenopathy (75%). Among five patients with air-leak complications, three had a history of allergies and three required the intensive care unit.
CONCLUSION:
Chest CT findings in children with S-OIV infection were peribronchial thickening and a mixture of airspace consolidation and GGO with random distribution and lower lobe predominance. Pleural effusion, lymphadenopathy, PIE, and pneumomediastinum may be associated findings.
