儿童肺炎支原体性肺脓肿的CT表现（附12例分析）

目的:研究儿童肺炎支原体性肺脓肿的CT表现.方法:回顾性分析本院12例肺炎支原体性肺脓肿患儿的临床资料和胸部CT表现.结果:12例早期均表现为肺实质渗出性痛变,随病程进展出现液化坏死及大小、数目不等的空洞;11例为单侧肺叶受累,1例为两侧肺受累;6例右肺受累,5例左肺受累;2例合并有胸腔积液及胸膜增厚.随访4～18个月10例肺实变完全吸收,肺坏死及空洞消失;2例仍有局限性肺不张,呈纤维条索样改变;2例胸腔积液完全吸收.结论:儿童肺炎支原体性肺脓肿早期表现为肺实变,随病程进展出现液化坏死及空洞,可有胸腔积液及胸膜反应,经积极治疗大部分可吸收好转.

CT features of mycoplasma pneumoniae lung abscess in children (with report of 12 cases)

Objective:To assess the CT imaging features of mycoplasma pneumoniae lung abscess in children.Methods:Clinical data and chest CT findings of 12 children with clmically confirmed mycoplasma pneumoniae lung abscess were analyzed retrospectively.Results:The imaging findings of all the patients were pulmonary consolidation in early stage and necrosis,cavity with variable size and number along with the progression.There was single lobe involvement in 11 cases and 2 or more lobes involvement in1 case,and involvement of right lung in 6 cases and of left lung in 5 cases.2 cases combined with pleural effusion and pleural thickening.Lung consolidation,necrosis and cavity completely absorbed in 10 cases,residual fibrotic change was seen in 2 cases,pleural effusion completely absorbed in all patients in follow up for 4～ 18 months.Conclusion:Lung abscess related to mycoplasma pneumoniae infection in children shows consolidation of the lungs in early stage,necrosis,cavity formation,pleural effusion and pleural thickening appeared along with the progression,recovery can be achieved in most cases after active treatment.
