【摘要】 目的  總結甲型H1N1流感病毒性肺炎患者的胸部X線和CT表現特征。 方法  回顧分析2009年3月-11月3例經臨床表現及病原學檢查證實的甲型H1N1流感病毒性肺炎的胸部X線、CT表現。 結果  肺部病灶多呈散在小片狀高密度影，邊緣模糊，鄰近胸膜；病變最常累及肺基底段；病灶多有少量胸腔積液；病灶有擴散迅速，合理用藥后消失較快的特點；病灶吸收落后于臨床表現。 結論  甲型H1N1流感病毒性肺炎的X線、CT表現具有一定的特點，總結并掌握這些特點，有利于早期診斷。其確診有賴于實驗室檢查和流行病學調查。
【Abstract】Objective  To explore the chest X-ray, CT manifestations of pneumonia of patients with influenza virus A/H1N1 infection. Methods  The pulmonary X-ray and CT findings of 3 patients who were confirmed by laboratory results and epidemiology with infection of influenza virus A/H1N1 were retrospectively analyzed between March 2009 to November 2009. Results  Both sides of the lung field showed many small cloudy infiltration in chest X-ray and CT film. The lesions of the lung were mostly near the pleural. They were often found in basal segment. Pleural effusion may be observed. Radiology dynamic changes showed the diffusion of the lesions of the lung was quick in a short time, and scattered and disappeared quickly after rational use of drugs. The lesions vanished later than clinical disappearance. The lesions of the lung may appear fibrosis at the period of the end. Conclusion  Some radiographic characteristics exist in the pneumonia of patients with influenza virus A/H1N1 infection. It will be helpful for early diagnosis when getting familiar with its X-ray and CT manifestations, but the final diagnosis depends on the laboratory results and epidemiological history.
