摘要
目的:探讨儿童重症肺炎支原体肺炎(MPP)的CT表现与临床预后的相关性。方法:选取40例重症MPP患儿作为研究对象,根据正规治疗后的病情转归将其分为预后良好组和预后不良组,比较两组患儿的胸部CT表现,如病灶部位、形态、密度、是否合并肺不张、胸腔积液、肺门或纵隔淋巴结肿大、空洞等。结果:40例重症MPP患儿中,19例表现为磨玻璃样密度影,22例表现为大片状实变影,12例表现为网格状改变伴小结节、斑片条索影;合并肺不张21例、胸腔积液17例、纵隔或肺门淋巴结肿大10例及坏死空洞1例。预后良好组31例,其中13例(41.9%)表现为大片状实变影,预后不良组9例,大片状实变影发生率为100%,两组的大片状实变影发生率具有统计学差异(P<0.05),其余影像学征象在两组间均无统计学差异(P均>0.05)。结论:胸部CT在儿童重症MPP预后评估中具有一定的临床价值,胸部CT表现为大片实变影的患儿预后可能较差。
Objective:To investigate the correlation between CT findings and clinical prognosis of children with severe mycoplasmal pneumonia.Methods:A total of 40 children with severe mycoplasmal pneumonia were included in this study.According to the outcome of patients after standard treatment,they were divided into a good prognosis group and a poor prognosis group.Chest CT imaging findings were retrospective analyzed of,including lesion site,morphology,density,whether complicated with atelectasis,pleural effusion,hilar or mediastinal lymph node enlargement,cavity,etc.Results:Among the 40 cases of children with severe mycoplasmal pneumonia,ground-glass-opacity was found in 19 cases,large-patchy solid lesions were found in 22 cases,and grid-like changes with small nodules and patchy shadows were found in 12 cases.21 cases got atelectasis,and 17 cases got pleural effusion,10 cases got mediastinal or hilar lymph node enlargement and 1 case of patient complicated with necrotic cavity.Among the 31 cases with good prognosis,13 cases(41.94%)showed large-patchy solid lesion.And among the 9 cases with poor prognosis,all had large-patchy solid lesion shadow(100%).The difference in incidence rate between the two groups was statistically significant(P<0.05),the differences in the rest imaging findings between the two groups were without statistically significant.Conclusion:Chest CT has a certain clinical value on the evaluation of prognosis in children with severe mycoplasmal pneumonia.Whose chest CT image feature with large patchy solid lesion shadows may have a poor prognosis.
