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 improve the clinical knowledge of various forms of atypical pulmonary tuberculosis and to avoid misdiagnosis and missed diagnosis. Methods 484 patients with pulmonary tuberculosis were examined by X - ray computed tomography (CT) radiography and chest computed tomography (CT). The chi - square test was used for statistical analysis. Results The percentage of atypical tuberculosis cases (44.0%) and atypical cases (40.0%) in patients aged 60-85 years were significantly higher than those in patients aged 15-59 years (33.8% vs 29.6%), with statistical difference significance. Compared with patients with simple pulmonary tuberculosis, the proportion of patients with diabetes, pneumoconiosis and AIDS complicated with pulmonary tuberculosis was significantly higher in the proportion of atypical parts and atypical lesions, with statistical difference. Conclusion The clinical and radiographic findings of atypical pulmonary tuberculosis are fully understood and valued to improve the diagnosis and treatment rate of pulmonary tuberculosis.
