摘要
目的探讨肺小叶结构异常高分辨率CT（HRCT）征象在表现为弥漫性结节病变的肺结核和肺癌诊断和鉴别中的价值。方法对150例肺结核、肺癌患者行HRCT检查，图像用高分辨重建。结果肺淋巴道转移癌小叶间隔异常表现为串珠状者60％和不规则状者40％，而血行播散性肺结核多表现为小叶间隔结节状改变，两者之间差别有统计意义（P〈0．05）。在小叶实质细线、网状影表现上．肺淋巴道转移癌占60％，与血行播散性肺结核（6.3％）、肺血行转移癌（6．7％）和弥漫结节性细支气管肺泡癌（7.1％）之间差别有显著性（P〈0.05）。83.3％支气管播散性肺结核表现为小叶中心“树芽征”，明显区别与血行播散性肺结核和弥漫结节性肺癌。结论肺小叶结构异常HRCT征象在弥漫结节性肺结核、肺癌诊断和鉴别中具有重要价值。
Objective The purpose of this study was to analyze the pulmonary lobular structure on HRCT of pulmonary tuberculosis and lung cancer with diffuse nodular and to assess the diagnostic value. Methods 150 cases underwent high resolution CT （HRCT） scans and the images were reconstructed using high-spatial-resolution algorithms. Results Pulmonary lymphangitic carcinomatosis exhibited beaded or irregular interlobular septa were 60%and 40%, respectively, there were significant difference between which and hematogenous disseminated pulmonary tuberculosis （P〈0.05）. Intralobular linear or fine reticular opacities in pulmonary lymphangitic carcinomatosis were 60%,different from the hematogenous disseminated pulmonary tuberculosis and pulmonary hematogenous metastases and diffuse nodular bronchioloalveolar carcinoma （P〈0.05）. 83.3% bronchogenicpulmonary tuberculosis shows centrilobular nodules and branching linear lesions （tree in bud）, significant differences between which and the hematogenous disseminated pulmonary tuberculosis or pulmonary metastases. Conclusion The HRCT signs on the pulmonary lobular abnormal structure have the important value in diagnosis and identification on pulmonary tuberculosis and lung cancer.
