Analysis of CT Imaging Characteristics in Children with Refractory Mycoplasma Pneumonia
Objective To explore the characteristics of computed tomography(CT)imaging in children with refractory mycoplasma pneumonia(RMPP).Methods A total of 74 children with mycoplasma pneumonia(MP)treated in the hospital were retrospectively enrolled between May 2020 and November 2023.According to presence or absence of RMPP,they were divided into refractory group(n=28)and common group(n=46).All patients underwent CT examination.The clinical data of all children were collected.The clinical characteristics and CT imaging characteristics in the two groups were compared.Results There was no significant difference in gender,clinical symptoms(shortness of breath,chest pain,dyspnea,cough)or inspiratory three-concave sign between refractory group and common group(P>0.05),but there were significant differences in age,length of hospital stay,fever duration,reduced respiratory sound and dullness in lung percussion(P<0.05).Among the 74 children with MP,there were 54 cases(72.97%)with unilateral lobar lesions(23 cases(42.59%)on the left side and 31 cases(57.41%)on the right side)and 20 cases(27.03%)with bilateral lobar lesions.There were 31 cases(41.89%)with single lobe lesions and 43 cases(58.11%)with multiple lobe lesions,and the main manifestations were pulmonary parenchymal lesions,pleural thickening,pleural effusion and bronchial wall thickening.There was no significant difference in the incidence of air bronchogram signs,spotty or patchy consolidation shadow and atelectasis between refractory group and common group(P>0.05).The incidence of bronchial wall thickening,tree bud sign,large consolidation shadow,pleural effusion and pleural thickening in refractory group was significantly higher than that in common group(P<0.05).Conclusion The clinical data and CT imaging examination are characteristic in children with RMPP,and the main manifestations include large consolidation shadow,pleural thickening,bronchial wall thickening,pleural effusion and tree bud sign.Clinically,the above CT signs can be applied in early diagnosis of RMPP.
