Objective To discuss the characteristics of computer tomography findings of chest from patients with influenza rnA ( H1N1 ) virus-associated pneumonia. and to improve understanding of this disease. Medthods We reviewed computer tomorngraphy findings of Fourty-one patients with influenza A ( H1N1) virus-associated pneumonia. Results The computer tomography rnfindings consisted of bilateral ground-glass opacities ( n = 37 ,90％ ) .consolidation( n= 12,29％ ) ,unilaterral( n= 6 , 15％ ) and birnlateral( n= 35 ,85％ ) .The areas of ill were found mainly in subplural and outer third of the lungs ( n= 39 ,95％ ) . and in middle rnand/or lower regions of the lungs ( n = 37 ,90％ ) . None had evidence of hilar or mediastinal lymph node enlargement on CT perrnformed in our study. Conclusion The predominant computer tomography findings consisted of unilateral and/or bilateral rnground-glass opacities with or without consolidation, which had a predominant distrihution of subplural and outer third, and in midrndle and/or lower regions of the lungs.%目的 探讨甲流相关肺炎胸部CT表现特征,提高对该疾病的影像学认识.方法 回顾分析41例甲流相关肺炎胸部CT特征.结果 甲流肺炎的胸部CT病变形态包括磨玻璃状阴影(n=37,90%),实变(n=12,29%),单侧肺受累(n=6,15%),双肺受累(n=35,85%),主要分布于中下肺(n=37,90%),肺野中外1/3及胸膜下(n=39,95%).没有发现肺门或纵膈淋巴结肿大患者.结论 甲型H1N1流感肺炎胸部CT以磨玻璃阴影及实变为主,单或双侧中下肺多见,主要累及肺野中外1/3及胸膜下.
