摘　　要：目的:分析儿童甲型H1N1流感患者胸部影像特点,为临床合理诊断和评价病情提供依据。方法:回顾性分析80例确诊甲型H1N1流感患者胸部影像资料及特点。患者图像资料由两位高年资医师独立阅片并达成一致意见。结果:甲型H1N1流感患者肺部影像特点8例X线表现正常;50例肺部X线表现为两肺下野斑片状影(10例病灶有融合);6例患者表现为大叶性肺炎;16例重症患者行胸部X线检查,均表现为两肺弥漫性大片状实变影,其中6例行CT平扫,表现为两肺弥漫性大片状实变影和肺间质改变;5例表现为两肺弥漫性大片状实变影者,3个月后HRCT复查显示小叶间隔增厚。结论:儿童甲型H1N1流感患者胸部影像多表现为两肺下斑片状阴影,其次为两肺弥漫大片状实变影,影像表现为正常或大叶状实质变性相对较少。Objectives：The aim of the present study was to analyze the chest imaging findings in children diagnosed as having influenza A （H1N1） infection. Methods： Nasopharyngeal-swabs and bronchial aspirate samples from 80 children with acute respiratory infections were tested positive for influenza A （H1N1） using quantitative real-time polymerase chain reac- tion. Chest images of these patients were analyzed retrospectively by two independent radiologists for the presence and dis- tribution of abnormalities. Results：Chest radiograph findings consisted of bilateral patchy areas of consolidation （n = 50）, diffuse areas of air-space consolidation （n= 16） and lobar consolidation （n= 6）. Chest X-rays of 8 cases were normal. Ab- normalities were observed more frequently in the lower lobes （bilateral, n= 66＇ unilateral, n= 6）. Computed tomography （CT） scans were performed on 6 cases with air-space consolidation and interstitial opacities. Cases with diffuse areas of air- space consolidation were followed-up after three month by high resolution CT imaging, which showed interstitial thicken- ing. Conelusion：The predominant imaging findings in childhood influenza A （H1N1） are bilateral patchy areas of consolida- tion,followed by diffuse areas of air-space consolidation,to a lesser extent, being normal radiographs, and lobar consolida- tion.
