484例肺结核患者的影像学变化分析

Analysis of radiological change of 484 patients with pulmonary tuberculosis

目的提高临床对各种形态不典型肺结核影像学的认识,避免误诊漏诊。方法应用胸部X线DR摄片及胸部CT对484例肺结核患者进行影像学检查,采用χ~2检验进行统计学分析。结果60~85岁患者结核病变为非典型部位比例(44.0%)和为非典型病变类型比例(40.0%)均大于15~59岁患者组(33.8%和29.6%),两者差异具有统计学意义。与单纯性肺结核患者比较,糖尿病、尘肺、艾滋病合并肺结核患者病变,非典型部位和非典型病变类型比例显著升高,有统计学差异。结论充分认识和重视不典型肺结核的临床及影像学表现,以提高肺结核诊治率。

Objective To enhance the recognition for sorts of atypical imagining features of pulmonary tuberculosis, and to avoid the misdiagnosis. Methods The X-ray and CT finding of 484 patients with pulmonary tuberculosis were studied by groups, X 2 test was used as the statistical analysis. Results The ratio of atypical location and configuration in radiograph in 60-85 years old group was higher than that in 15-59 years old group,there was statistic difference between two groups. In comparison with patients with pure pulmonary tuberculosis, the rates of patients with pulmonary tuberculosis and diabetes/AIDS/silicosis were statistically higher in the atypical location and configuration. Conclusion It is important to fully understand and pay attention to the atypical pulmonary tuberculosis radiological manifestations, in order to improve the rates of diagnosis and treatment.
