成人肺炎支原体肺炎的CT表现

CT manifestations of adult mycoplasma pneumoniae pneumonia

目的 认识成人肺炎支原体肺炎的CT及高分辨率CT(HRCT)表现。方法 16例经血清学检查证实的成人肺炎支原体肺炎 ,平均年龄 41岁。回顾分析了所有病例的胸部常规CT及HRCT。结果 最常见的CT表现为磨玻璃样影 12例 ,其中 9例呈斑片状小叶分布 ;8例表现为气腔实变 ;9例可见“树芽征” ;其他表现有小叶间隔增厚 3例 ,支气管血管束增粗 1例等。 15例同时出现 2种以上CT表现。结论 成人肺炎支原体肺炎的CT表现具有一定特征性 。

Objective To study the conventional CT and HRCT manifestations of adult mycoplasma pneumoniae pneumonia. Methods Conventional CT and HRCT were performed in 16 adult patients with mycoplasma pneumoniae pneumonia proven by serology. The CT images were retrospectively analyzed. Results Areas of ground glass opacity(GGO)were found in 12 cases. GGO showed lobular or patchy distribution in 9 cases. Air space consolidation was observed in 8 cases,'tree in bud' sign in 9,thickening of the interlobular septa in 3,and thickening of bronchovascular bundle in 1. 15 cases had two or more findings simultaneously. Conclusion Mycoplasma pneumoniae pneumonia has some characteristic CT findings, which can help to distinguish it from bacterial pneumonia.
