A região mais frequentemente envolvida foi o terço médio, com distribuição central e periférica e ausência de derrame pleural. Resultados:Ī anormalidade encontrada com maior frequência na radiografia de tórax foram as marcas peribroncovasculares, a maioria delas com extensão menor de 25% do pulmão, envolvimento bilateral e assimétrico. A população estudada foi dividida em dois grupos: sem suporte ventilatório e com suporte ventilatório e/ou óbito. Os achados radiológicos foram caracterizados por tipo e padrão de opacidade e distribuição por zonas pulmonares. Os pacientes foram examinados entre 2012 e 2016 e o diagnóstico foi estabelecido por critérios clinicorradiológicos e detecção do vírus por reação em cadeia de polimerase. Revisamos, retrospectivamente, os achados na radiografia de tórax de 17 casos de infecção pulmonar pelo vírus influenza (7 do sexo masculino e 10 do sexo feminino idade média de 14 meses, variação de 2 a 89 meses). Influenza, human Influenza A virus, H1N1 subtype Radiography, thoracicĪvaliar os achados na radiografia de tórax de pacientes com diagnóstico de infecção pelo vírus influenza. Although the definitive diagnosis of H1N1 virus infection cannot be made on the basis of imaging characteristics alone, using a combination of clinical and radiographic findings can substantially improve the diagnostic accuracy. In pediatric patients with H1N1 virus infection, the main alterations on the initial chest X-rays are peribronchovascular opacities, nonspecific alveolar opacities, and consolidations. There was a statistically significant difference between the groups in terms of the symmetry of pulmonary involvement, asymmetric findings predominating in the group that required ventilatory support ( p = 0.029). The lung zone most frequently involved was the middle third, with central and peripheral distribution, without pleural effusion. The abnormality most often seen on chest X-rays was that of peribronchovascular opacities, the majority of which affected less than 25% of the lung, the involvement being bilateral and asymmetric. The patients were divided into two groups: those not requiring ventilatory support and those requiring ventilatory support or evolving to death. The radiographic findings were categorized by type/pattern of opacity and by lung zone. The diagnosis was established on the basis of clinical and radiographic criteria, and the virus was detected by polymerase chain reaction. The mean age of the patients was 14 months (range, 2-89 months). We retrospectively reviewed chest X-ray findings in 17 cases of pulmonary infection with the H1N1 virus (in 7 males and 10 females) examined between 20. To evaluate chest X-ray findings in pediatric patients diagnosed with influenza A (H1N1) virus infection.
