Imaging findings and therapeutic evaluation of pneumonia caused by human infected H7N9 avian influenza virus

Abstract

Abstract: Objective The purpose of this study was to characterize the clinical and radiological findings of H7N9 avian influenza virus infection. Methods A retrospective review of 37 patients suffering from H7N9 avian influenza virus infection was performed.Thoracic X-ray and CT results of the patients and clinical data were available. Results 5 patients had absolutely contact with avian. Consolidation lesions and GGOs were found in the lungs of all 37 patients,and all consolidation and GGOs absorbed quickly after antiviral therapy. After treatment,streaks and interlobular septa thickening were both found in 33 patients.Pleural arcs were found in 16 patients. Conclusion The most common imaging findings were consolidation and GGOs in the lungs of patients with H7N9 avian influenza virus infection. After treatment of antiviral therapy,most of the lesions absorbed quickly,and a small number of the lesions such as streaks left in the lung,suggesting early lung fibrosis.
