目的:分析研究儿童肺炎支原体肺炎不同年龄段患儿的影像学特点,为临床诊断儿童支原体肺炎提供参考。方法:选择2011年8月~2013年9月该院收治的明确诊断为儿童肺炎支原体肺炎患儿128例为临床研究对象,所有患儿在临床诊断过程中均使用了影像学诊断,包括X线及CT检查。将患儿分为<1岁组(43例)、1~3岁组(35例)和>3岁组(40例)。比较3组患儿的影像学特点。结果:>3岁组影像学表现以大片状高密度影为主,与其他两组比较,差异有统计学意义(P<0.05)。<1岁组患儿出现双侧肺部受累比例最高,>3岁组比例最低,与其他两组比较,差异有统计学意义(P<0.05)。结论:在儿童肺炎支原体肺炎的影像学表现较为多样,<3岁婴幼儿主要为小斑片阴影,并多累及到双侧肺部;>3岁主要为大片影,且以单侧受累为主。
Objective: To analyze the imaging characteristics of children with mycoplasma pneumoniae pneumonia at different ages and to provide reference for clinical diagnosis of children with mycoplasma pneumoniae. Methods: A total of 128 children with mycoplasma pneumoniae pneumonia were selected from August 2011 to September 2013 in our hospital for clinical study. All children underwent imaging diagnosis during the clinical diagnosis, including X-ray And CT examination. Children were divided into <1 year old group (43 cases), 1 to 3 years old group (35 cases) and> 3 years old group (40 cases). The imaging features of the three groups were compared. Results: The imaging findings of> 3 years old group were dominated by large, high-density and high-density, and the difference was statistically significant (P <0.05) compared with the other two groups. <1 year old children had the highest proportion of bilateral lung involvement, the lowest was> 3 years old, and the difference was statistically significant (P <0.05) compared with the other two groups. Conclusions: The manifestations of mycoplasma pneumoniae pneumonia in children are quite diverse. The infants younger than 3 years are mostly small patchy shadows and are involved in the bilateral lungs. The lesions of> 3 years old are mostly large and mainly unilateral .
