Abstract:
Objective To evaluate the imaging features of pneumonia caused by A (H1N1) influenza virus. Methods Imaging data of 51 patients with pneumonia caused by A H1N1 influenza were retrospectively reviewed. All patients underwent mobile chest radiographs and 44 patients underwent CT as well. On the basis of the lesion degree in the lung, the patients were classified into mild, moderate and serious types. Results Mild type showed patchy consolidation at chest imaging in 4 patients. Moderate type demonstrated consolidation and(or) ground -glass opacities more than 2 lung fields in 33 patients, including 30 bilateral and 3 unilateral. Serious type displayed diffuse consolidation and ground-glass opacities, probably accompanying with interstitial lesions in the lungs in 14 patients, including 6 patients with ARDS, 2 with infection and 1 with cutaneous emphysema. Conclusion The imaging features of pneumonia caused by A H1N1 influenza mainly manifest as consolidation and ground-glass opacities, probably accompanying with interstitial changes. The imaging findings show various in patients with infection. Some serious patients even develope to ARDS.
