摘要 目的分析儿童肺炎支原体肺炎(MPP)的胸部CT影像学特点,指导临床早期诊断治疗。方法回顾性分析2007年1月-2008年12月间64例诊断明确的MPP患儿的临床资料及胸部CT。结果①64例患者中,男35例(58.6%),女29例(41.4%)。年龄(1岁2例(3.1%),1~3岁14例(21.8%),4~7岁18例(28.1%),8~10岁20例(31.2%),(10岁10例(15.6%)。②病变影像局限于单侧的病变中,右侧30例(69.8%),左侧13例(30.2%),右侧明显多于左侧;多个叶段受累(65.5%)多于单个叶段受累(34.3%);各叶段受累情况分析以右下叶最多,共22例(34.2%),其次为右中叶(18.7%)、左上叶(18.7%)。③病变影像以大片实变影最多(84.3%),余分别为胸腔积液(31.2%)、肺不张(25.0%)、肺门淋巴结肿大(15.6%)和散在斑片状影(12.5%),年龄不同影像改变也有一定差异。结论儿童MPP年长儿发病率高于婴幼儿,右肺发病多于左肺,大片实变影最多,其影像特点与年龄有关,胸部CT影像学特点有助于儿童MPP的诊断。 Objective To analyze the chest CT imaging characteristics of Mycoplasma pneumoniae pneumonia(MPP) in children and guide the preliminary clinical diagnosis of MPP. Methods The chest CT scans and clinical data obtained from 64 children with MPP were retrospectively analyzed. Results ①There were 35 eases (58.6%) of male and 29 cases (41.4%) of female among the 64 patients. 2 eases were under 1 years of age, 14 eases 1-3 years, 18 eases 4-7 years,20 eases 8-10 years and 10 eases over 10 years old. ②In the 43 eases with unilateral abnormalities, there were 30 eases with abnormalities in right lung, and 13 eases with abnormalities in left one. The abnormalities in fight lung were more frequent than those in left one. Multiple areas abnormalities were more than single areas. The abnormalities in right lower lobes(34.2% ) were most frequent in all cases when compared with the other lobes. Secondly,the abnormalities in middle lobe of right lung( 18.7% ) and upper lobe of left lung( 18. 7% ). ③A large area of consolidation on CT was identified in 84.3% of the patients and other CT imaging characteristics included pleural effusion( 31.2% ), ateleetasis (25 % ), hilar lymph node enlargement( 15.6% ) and scattered patchy consolidation. CT imaging characteristics was different in children of different ages. Conclusion The morbidity rate of MPP in older children was significantly higher than that in infant. The abnormalities in the right lung were more frequent than those in the left one. The large area of consolidation was most frequent in all cases. The characteristics of its chest CT image can provide some hints for the diagnosis of MPP.
