儿童细菌性肺炎影像特点及其临床价值

Radiologic features of pediatric bacterial pneumonia and its clinical value

细菌性肺炎为儿童社区获得性肺炎的重要组成部分,尤其多见于婴幼儿。如治疗不及时,病死率较高。影像检查可在儿童细菌性肺炎的诊疗中发挥一定作用,主要征象包括肺泡浸润灶、肺不张、胸膜渗出、肺大疱和间质改变。对于某些特殊病原菌感染(如金黄色葡萄球菌肺炎、肺炎链球菌肺炎及流感嗜血杆菌肺炎),可经典型影像特点和临床表现进行推断,对临床诊疗有所帮助。

Pediatric bacterial pneumonia is the important components of community-acquired pneumonia in children,especially in newborn and infants. The mortality is increased if left untreated. The radiologic examination may play a role in diagnosis and treatment of pediatric bacterial pneumonia,and the major signs include alveolar infiltration,atelectasis,pleural effusion,bullae of lung and interstitial changes. To some pneumonias caused by special pathogens,the diagnosis cab be made be the typical radiologic features combined with clinical presentations,which is helpful to the treatment.
