Abstract: 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.
