【摘要】 目的 总结甲型H1N1流感病毒性肺炎患者的胸部X线和CT表现特征。 方法 回顾分析2009年3月-11月3例经临床表现及病原学检查证实的甲型H1N1流感病毒性肺炎的胸部X线、CT表现。 结果 肺部病灶多呈散在小片状高密度影,边缘模糊,邻近胸膜;病变最常累及肺基底段;病灶多有少量胸腔积液;病灶有扩散迅速,合理用药后消失较快的特点;病灶吸收落后于临床表现。 结论 甲型H1N1流感病毒性肺炎的X线、CT表现具有一定的特点,总结并掌握这些特点,有利于早期诊断。其确诊有赖于实验室检查和流行病学调查。
【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.
