儿童H5N1型禽流感病毒性肺炎的胸部X线表现(附确诊及疑似病例各一例)

目的 描述儿童高致病性H5N1型禽流感病毒性肺炎患者的胸部X线表现。方法 回顾性分析1例经世界卫生组织确认为H5N1型禽流感病毒感染患者及1例疑似患者的胸部X线表现。结果 2例患者的胸部X线表现特点为：两肺大致对称、广泛分布的团絮状及大片状渗出病变，密度较高，边缘模糊；动态观察短期内病灶形态变化快，呈游走性；后期遗留纤维化病变。结论 儿童高致病性H5N1型禽流感病毒性肺炎的动态胸部X线表现具有定特征性。熟悉其胸部X线表现有助于该病的诊断，但最终确诊须依靠流行病学史及实验室检查。

The chest X-ray manifestations of children with highly pathogenic H5N1 avian influenza virus infection (a report of 1 final diagnosis case and 1 borderline case)

Objective To describe the chest X-ray manifestations of children with highly pathogenic H5N1 avian influenza virus infection. Methods The pulmonary X-ray findings in 1 patient was confirmed by the World Health Organization infected H5N1 avian influenza virus arid 1 borderline patient was retrospectively analyzed. Results Both sides of lung field showed the cloudy and massive infiltration in chest X-ray fihn. The lesions of lung distributed extensively and symmetricully. Radiologicul dynamic changes showed the variation of the lesions of lung was quick in a short time. it had a characteristic of roving around. The lesions of lung appeared fibrosis at the period of the end. Conclusion There are some radiographic characteristics in children with H5N1 avian influenza virus infection, it will be helpful for its diagnosis when getting familiar with its X-ray manifestations, but the final diagnosis is dependent on the epidemiology history and laboratory results.
