摘要
目的探讨儿童支原体肺炎的胸部影像学特征,并提供有助于临床诊断的信息。方法选择2015年1月-2016年1月我院儿科住院患儿126例,回顾性分析其影像学表现。结果 1岁以下年龄组患儿20例,1-3岁组28例,3岁以上组78例,三组影像学表现均以磨玻璃密度斑片影为主,三组患儿肺部CT表现以支气管充气征及淋巴结增大为主,1岁以下年龄组中3例发生于左侧,1例发生于右肺,16例发生于双肺;1-3岁组中3例发生于左侧,5例发生于右肺,20例发生于双肺;3岁以上组中24例发生于左侧,29例发生于右肺,25例发生于双肺,<1岁组、>3岁组两组相比,肺部受累情况有显著统计学差异(χ~2=15.569,P<0.001),1-3岁组、>3岁组两组相比,肺部受累情况有显著统计学差异(χ~2=13.177,P=0.001)。<1岁组、1-3岁组患儿病变多发生于双肺。结论儿童支原体肺炎有一定的影像学特点,主要表现为磨玻璃密度斑片影的间质性改变及支气管充气征,更容易出现淋巴结肿大。
Objective To discuss the chest imaging characteristics of children with mycoplasma pneumonia, in order to improve the comprehension of the imaging findings disease and provide scientific basis for clinical diagnosis and severity assessment. Methods The chest CT images of 126 children from January 2015 to January 2015 were retrospectively analyzed. Results There were 20 cases under 1 year old, 28 cases of 1 -3 years old, and 78 cases older than 3 years old. The imaging findings were mainly ground glass opacity, and their lung CT manifestations mainly included air-filled bronchi and lymph node enlargement in the three groups. In the younger than 1 year old group, 3 cases mainly occurred in the left lobe, 1 case occurred in the right, and 16 cases occurred in double. In the 1 - 3 years old group, 3 cases mainly occurred in the left, 5 cases occurred in the right, and 20 cases occurred in both. In the older than 3 years group, 24 cases occurred in the left, 29 cases occurred in the right, and 25 cases occurred in both. There were significant difference in lung involvement situation between the youngest group and the oldest group （chi-square = 15. 569, P 〈 0. 001 ）, and between the middle group and the oldest group. Conclusion Children with mycoplasma pneumonia has certain imaging characteristics, mainly showing ground glass opacity of interstitial change and air-filled bronchi, more prone to lymph node enlargement.
