We aimed at evaluating the relationship between microbial etiology and chest radiograph appearance in various types of pneumonia. In a prospective study, the radiographic findings in 479 cases of acute pneumonia in children were compared with viral etiology and growth of potential bacterial pathogens in nasopharyngeal secretion. As the basis for viral etiology was most conclusive, the material was here classified according to the viral findings. The patients were divided into three age groups: 0-2, 3-5 and 6-15 years. The chest radiograms were analyzed blindly for the presence of hyperinflation and interstitial, alveolar and mixed interstitial-alveolar infiltrates. There was a statistically significant relationship between low age and occurrence of hyperinflation and interstitial infiltrates, and between high age and alveolar infiltrates. No unequivocal relationship was found between type of infiltrates or presence of atelectasis and proven viral etiology. We conclude that chest radiographs are not a useful indicator of microbial etiology in childhood pneumonia.
我们旨在评估各类肺炎中微生物病因与胸部X光片表现之间的关系。在一项前瞻性研究中，将479例儿童急性肺炎的X光检查结果与病毒病因以及鼻咽分泌物中潜在细菌病原体的生长情况进行了比较。由于病毒病因的依据最为确凿，因此此处根据病毒检测结果对病例进行分类。患者被分为三个年龄组：0 - 2岁、3 - 5岁和6 - 15岁。由专人对胸部X光片进行分析，以确定是否存在肺过度充气以及间质、肺泡和间质 - 肺泡混合性浸润。年龄小与肺过度充气和间质浸润的发生之间存在统计学上的显著关系，年龄大与肺泡浸润之间存在统计学上的显著关系。未发现浸润类型或肺不张的存在与已证实的病毒病因之间存在明确关系。我们得出结论，胸部X光片并非儿童肺炎微生物病因的有用指标。
