摘要
目的分析急性粟粒型肺结核(AMPT)和粟粒性肺转移瘤(MLM)的常规CT及高分辨CT(HRCT)扫描中的特征。方法回顾性分析25例AMPT和30例MLM的常规CT及HRCT资料,观察小结节的特点及其他并发征象。结果结节的大小、密度、分布及边界在AMPT、MLM间差异无统计学意义(P>0.05);肺内磨玻璃密度、肺实变在AMPT的发生率高于MLM(P<0.05);多发结节小空洞、小叶间隔增厚、胸膜增厚及淋巴结增大在MLM的发生率高于AMPT(P<0.05)。结论AMPT和MLM的CT表现有一定特征,有助于对两者的鉴别诊断。
Objective To analyze routine CT and high-resolution CT （HRCT） characteristics of acute miliary pulmonary tuberculosis （AMPT） and miliary lung metastases （MLM）. Methods CT and HRCT data of 25 patients with AMPT and 30 with MLM were retrospectively reviewed; nodular characteristics and other complicated findings were observed. Results No difference was found in size, density, distribution and margin of miliary nodule between AMPT and MLM （P〉0. 05）. Ground-glass opacities and consolidation in AMPT was more than those in MLM （P〈0.05）, while multiple small cavitates, interlobular septal thickening, pleural thickening and lymph node increasing were more obvious in MLM than in AMPT （P〈0.05）. Conclusion CT characteristics of AMPT and MLM are different and contribute to the differential diagnosis of the two diseases.
