摘　　要：目的分析MSCT检查对儿童肺炎支原体肺炎(MP)与肺炎支原体肺炎合并肺炎链球菌感染肺炎(SP)的鉴别诊断价值。方法回顾性分析2017年4月至2019年7月收治的76例MP和MP+SP患者的临床资料,观察MP和MP+SP两组患者的MSCT表现,并比较气道和肺间质病变征象的出现率及肺内病变形态出现率。结果两组患者磨玻璃影、网状影、支气管壁增厚、支气管血管束增厚出现率比较差异具有统计学意义(P<0.05),但两组支气管充气相和肺气肿出现率比较差异无统计学意义(P>0.05);MP组28例出现扇形薄片影,10例无规律肺内实变影;MP+SP组5例出现扇形薄片影,33例无规律肺内实变影(P<0.05)。结论MSCT检查可有效显示MP与MP+SP图像表现,根据MSCT图像表现可有效鉴别MP与MP+SP。Objective To analyze the differential diagnosis value of MSCT examination for mycoplasma pneumonia(MP)and mycoplasma pneumonia combined with streptococcus pneumonia(MP+SP)in children.Methods The clinical data of 76 patients with MP or with MP+SP admitted from April 2017 to July 2019 were retrospectively analyzed.The MSCT characteristics of patients with MP or MP+SP were observed,and the incidence of lesion signs of airway and pulmonary mesenchyme and the incidence of lesions form in the lung were compared.Results There was a statistically significant difference in the incidence of ground-glass shadow,reticular shadow,thickening of bronchial walls,and thickening of bronchovascular bundles between the two groups(P<0.05),but there was no significant difference in the incidence of air bronchogram sign and emphysema between the two groups(P>0.05).In the MP group,28 cases showed fan-shaped flaky shadow,10 cases showed irregular intrapulmonary solid change shadows.In the MP+SP group,5 cases showed fan-shaped flaky shadow,33 cases showed irregular intrapulmonary solid change shadows(P<0.05).Conclusion The MSCT examination can effectively display the image features of MP and MP+SP,and can effectively distinguish MP from MP+SP according to the characteristics of MSCT images.
