摘要
目的通过对小儿肺炎支原体肺炎（mycoplasma pneumoniae pneumonia,MPP）的肺部影像学资料进行总结,分析其影像学特点。方法回顾2013-05/2014-07月于作者医院住院,确诊为MPP的临床及影像资料完整的患儿81例,其中男40例,女41例,年龄1-14（5.86±3.25）岁,对肺部影像学资料进行归纳总结。结果所有患儿均有肺部异常影像学改变。位置分布情况上,〈5岁组以双肺病变为主,≥5岁组以右肺为主。肺部影像学主要有3种类型：散在淡片状影占61.73%（50/81）、片状高密度影占12.35%（10/81）、间质浸润性改变占25.93%（21/81）。间质浸润性病变发生率,小于5岁组高于≥5岁组,淡片状影和片状高密度影两组比较无统计学意义（P〉0.05）。持续高热患儿其影像学改变往往表现为片状高密度影（8例）,可伴有胸膜反应（2例）或胸腔积液（1例）。肺纹理增强、模糊一般在病后3-4 d出现,淡片状模糊影多出现在病后1周左右,肺实变及胸膜反应的改变多出现在病后10 d左右。结论 MPP其影像学表现具有一定的特征性,临床高度怀疑肺炎支原体感染者,均应及早做胸部影像学检查,为临床早期诊断和治疗提供依据,以免漏诊。
Objective To analyse the lung imaging data of the children with mycoplasma pneumoniae pneumonia（MPP）and summarize the characteristics.Methods The complete clinical and imaging data of 81 MPP children from January 2013 to July 2014 in the hospital,including 40 males and 41 females,1-14（5.86±3.25）years old,were reviewed.Results All the patients had abnormal lung pathology image.5 years old group mainly had double lung lesions and more than 5 years old group mainly had right lung lesions.There were mainly 3imaging types：scattered light patchy shadow accounted for 61.73%（50/81）,high density shadow accounted for 12.35%（10,81）,interstitial infiltrating changes accounted for 25.93%（21/81）.The incidence of interstitial infiltrating lesions in5 years old group was higher than that of≥5 years old group,and was not different between groups with light patchy shadow and high density shadow.Children with persistent high fever often showed patchy high density shadow（8 cases）accompanied by pleural reaction（2 cases）or pleural effusion（1 case）.Increased lung texture and fuzziness generally occurred 3-4 days after disease onset,light patchy fuzzy shadow appeared 1 week after disease onset,and pulmonary consolidation and pleural reaction changes appeared 10 days after disease onset.Conclusion The imaging MPP has certain characteristics.Patients with suspected pneumonia mycoplasma infection should acquire early chest imaging of to supply reference for early diagnosis and treatment.
