摘要
目的研究学龄期肺炎支原体肺炎(MPP)患儿高分辨CT(HRCT)特点及其与肺功能关系。方法回归性分析医院2017.12~2018.12间收治的63例MPP患儿肺功能及肺部HRCT检查资料,总结其HRCT影像特点,并分析其与肺功能关系。结果HRCT检查提示,MPP患儿病变主要集中在肺野右下侧,79.37%的患儿发生肺实质病变,80.95%存在小气道改变,68.25%出现支气管充气征,65.08%出现支气管壁增厚,少数患儿有磨玻璃影改变、淋巴结肿大、胸腔积液等表现;不同肺实质病变程度MPP患儿FVC、FEV1及PEF间差异不显著(P>0.05),而FEF25、FEF50及FEF75水平随肺实质病变程度的加重逐渐降低,组间差异显著(P<0.05)。结论MPP患儿肺功能明显下降,其肺部HRCT影像学表现多样,以肺实质病变、小气道改变、支气管充气、支气管壁增厚为主,而肺实变程度与患儿肺功能障碍存在一定关系,能一定程度反应患儿肺部功能。
Objective To study the features of high-resolution computed tomography(HRCT)and their relationship with pulmonary function in children patients with schoolage mycoplasma pneumoniae pneumonia(MPP).Methods The examination data of pulmonary function and pulmonary HRCT of 63 MPP children patients admitted to the hospital from December 2017 to December 2018 were given regression analysis.The HRCT imaging features were summarized,and their relationship with pulmonary function was analyzed.Results HRCT examination showed that the lesions of MPP children patients were mainly concentrated in the lower right side of lung field,and there were 79.37%of children with pulmonary parenchymal lesions,80.95%with small airway changes,68.25%with bronchial hyperemia,and 65.08%with bronchial wall thickening,and a small number of children patients were with ground-glass opacity changes,lymphadenectasis and pleural effusion.There were no significant differences in the FVC,FEV1 and PEF among MPP children patients with different pulmonary parenchymal lesions(P>0.05),and the levels of FEF25,FEF50 and FEF75 were gradually decreased with aggravation of pulmonary parenchymal lesions(P<0.05).Conclusion The pulmonary function of MPP children patients is significantly decreased,and pulmonary HRCT imaging findings are diverse,mainly pulmonary parenchymal lesions,small airway changes,air bronchogram and bronchial wall thickening.The degree of pulmonary consolidation has a certain relationship with pulmonary dysfunction,and can reflect the pulmonary function of children patients.
