摘 要:目的:探讨数字X线胸部摄影对小儿肺炎支原体肺炎的诊断价值。方法:对41例血清IgM抗体滴度升高4倍以上的患儿的初次胸部X线平片影像表现进行回顾性分析。结果:37例(90.3%)显示段、叶性分布实变影,8例(19.5%)显示结节样小叶气腔实变,19例(46.3%)显示支气管血管束周围浸润。4例(9.7%)病变累及双肺,30例(73.2%)累及下肺野。第2次抗体滴度≥1280的患儿肺内病变累及范围大于第2次抗体滴度≤640的患儿(χ2=8.789,P=0.003)。结论:叶段分布气腔实变、支气管血管束周围浸润是小儿肺炎支原体肺炎最常见的胸部X线影像表现,结节样小叶中心气腔实变显示率较低。肺炎支原体抗体滴度升高程度可能与肺内病变的严重程度有关。Objective:The purpose of the study was to evaluate the role of chest digital radiography in children with mycoplasma pneumonia.Methods:We retrospectively studied the initial chest digital radiography of 41 cases with mycoplasma pneumonia,whose serum IgM antibody titers increased by four folds.Results:37cases(90.3%)showed lobar or segmental consolidation,8cases(19.5%)demonstrated nodular centrilobular or lobular consolidation,9cases(46.3%)showed peribronchial/perivascular interstitial infiltration.4cases(9.7%)had the lesions distributed bilaterally,30cases(73.2%)had the lesions involved lower lung field.The range of lesions in those patients with IgM antibody titers≥1280in the 2nd round were larger than that in those with IgM antibody titers≤640(χ^2=8.789,P=0.003).Conclusions:The radiographic manifestations of pediatric mycoplasma pneumonia varied.Lobar or segmental consolidation,peribronchial/perivascular interstitial infiltration were the most common findings.Nodular centrilobular/lobular consolidation were relatively rarely assessed.The level of antibody titer was suggested to have positive relationship with the degree of seriousness of pulmonary lesions.
