小儿非细菌感染性肺炎的X线分析(附218例报告)

目的　研究小儿非细菌感染性肺炎的X线特征。方法　流感病毒、副流感病毒、呼吸道合胞病毒 (RSV)、腺病毒 (AV )、肺炎支原体 (MYCO)、衣原体感染性肺炎共 2 18例。单一病原感染 15 2例 ,复合感染 66例。所有病例均摄有胸部X线片 ,12 9例随访 2次以上 ,平均随访间期 7d。按病原分类对其X线表现进行分析。结果　X线表现肺纹理增多 197例 ,肺纹理紊乱 187例 ,肺纹理僵直 10 5例 ,肺纹理模糊 194例。肺门影增大 91例 ,肺门模糊 93例。肺气肿 82例 ,斑点影 81例 ,肺透光度减低呈雾状影 3 4例 ,片状影 3 3例。 12 9例随访结果完全吸收 9例 (6.97% ) ,部分吸收 5 6例 (4 3 .41% ) ,无吸收 5 3例 (4 1.0 8% ) ,病变进展 7例 (5 .42 % )。结论　支原体肺炎、呼吸道合胞病毒肺炎有一定X线特征。非细菌感染性的间质性肺炎吸收间期最短不少于 7d。

Radiologic Analysis of Non-bacteria Infectious Pneumonia in Children(A Report of 218 Cases)

Objective To study the X-ray characteristic of non-bacterial infectious pneumonia in children.Methods In 218 cases of non-bacteria infectious pneumonia, the pathogenic agents included influenza virus,parainfluenza virus,respiratory syncytial virus(RSV),adenovirus,mycoplasma(MYCO) and chlamydia.Of them,mono-pathogenic infection were 152,mixed infection were 66.All the cases had chest conventional radiograph,129 cases were followed up for 2 times or more.The average period of the follow up were 7 days.The findings of chest conventional radiograph were analysed.Results The radiographic features included lung marking heavy 197,disorder 187,straight 105 and obscure 194;pulmonary hilum enlarged 91,hilum obscure 93,emphysema 82,point opacities 81,pulmonary radio-translucent diminution 34,patch opacities 33.In 129 cases followed up the lesions were perfectly absorbed 9(6.97%),partly absorbed 56(43.41%),non-absorbed 53(41.08%),progress 7(5.42%).Conclusion The absorbed period of non-bacteria infectious pneumonia is more 7 days.There are some radiographic characteristcs in RSV and MYCO pneumonia.
