238例水痘患者肺部影像学分析

Pulmonary imaging analysis of 238 patients with varicella

目的:分析原发性水痘肺炎的影像学表现及发病特点,提高对该病的认识。方法:回顾性分析238水痘患者的肺部X线平片和CT图像,总结原发性水痘肺炎的影像学特点并将X线及CT图像进行对照分析。结果:水痘肺炎的CT影像学表现分为粟粒型、结节型、斑片型。23例粟粒型水痘肺炎患者的胸部X线平片正常,结节及斑片型肺部病变两种方法检出率相同。水痘肺炎发病占同期水痘感染的比例为95.2%(220/231),发病率男性高于女性,差异有统计学意义(P<0.05),成人高于儿童,差异无统计学意义(P>0.05)。结论:双肺结节为水痘肺炎的典型影像学表现,粟粒型肺炎X线平片诊断存在假阴性,需结合CT检查。

Objective:By analyzing the imaging manifestations and characteristics of primary varicella pneumonia to improve the understanding of the disease.Methods:The X-ray and CT images of 238 patients with varicella were analyzed retrospectively.The imaging manifestations of primary varicella pneumonia were summarized and features between X-ray and CT images were compared.Results:The CT imaging manifestations of varicella pneumonia were divided into miliary type,nodular type and patchy type.The chest X-ray plain films of 23 patients with miliary type were normal.The detection rate of nodular and patchy using X-ray plain films was similar to that of CT.The incidence of varicella pneumonia accounted for 95.2%(220/231)of varicella virus infection in the same period,and male predominated(P<0.05).The incidence rate of adults was higher than that of children without statistically significant(P>0.05).Conclusion:Bilateral pulmonary nodules are typical imaging findings of varicella pneumonia.The X-ray plain film diagnosis of miliary pneumonia has false negative,which should be combined with CT examination.
