摘要
目的探索儿童支原体肺炎(MPP)的多层螺旋CT(MSCT)诊断价值。方法回顾性分析2022年01月-2023年07月我院确诊为支原体肺炎的患儿87例,总结其CT影像学特征。结果将患儿分为幼儿组(1-3岁)25例,学龄前组(学龄前)33例,学龄期组(学龄期)29例。三组患者病灶的分布均以两肺为主,三组间小叶间隔增厚存在显著统计学差异(χ^(2)=11.057,P=0.004),树雾征、树芽征、大叶实变等特征组间无统计学差异,患儿均未发现淋巴结肿大及胸腔积液。结论儿童支原体肺炎有一定的影像学特点,往往累及双肺,主要表现树雾征、树芽征、磨玻璃密度影、支气管壁增厚等征象,而很少有淋巴结肿大及胸腔积液。
Objective To explore the diagnostic value of multi-slice spiral CT(MSCT)in children with mycoplasma pneumonia(MPP).Methods We retrospectively analyzed 87 children with MPP diagnosed in our hospital from January 2022 to July 2023,and summarized their imaging features.Results The patients were divided into infant group(1-3 years old)with 25 cases,preschool group(preschool)with 33 cases and school-age group with 29 cases.The distribution of lesions in the three groups was mainly in both lungs.There was a significant statistical difference in interlobular septal thickening among the three groups(χ^(2)=11.057,P=0.004),but there was no statistical difference among the characteristic groups such as tree fog sign,tree bud sign and lobar consolidation.No lymphadenopathy and pleural effusion were found in the children.Conclusion MPP in children has certain imaging characteristics,often involving both lungs,mainly showing signs such as tree fog sign,tree bud sign,ground glass density shadow,thickening of bronchial wall,and few lymph node enlargement and pleural effusion.
