摘　　要：目的 :探讨肺内多发小结节的CT特征 ,提高CT诊断的准确性。方法 :回顾性分析经病理或临床证实的 5 3例肺内多发小结节患者的CT分布特征 ,其中血行性肺转移瘤 15例 ,粟粒性肺结核 8例 ,癌性淋巴管炎 10例 ,矽肺 3例 ,肺结核支气管播散 10例 ,细支气管肺泡癌 7例。结果 :血行性肺转移瘤、粟粒性肺结核、细支气管肺泡癌小结节呈随机分布 ;癌性淋巴管炎、矽肺小结节沿淋巴管周围分布 ;肺结核支气管播散呈小叶中心分布。结论Objective:To study the CT characteristics of pulmonary multiple nodules to improve its diagnostic accuracy.Methods:The CT findings of 53 cases with pulmonary multiple nodules (including 15 cases of hemtogenous dissemination of tumor metastasis,8 cases hemtogenous dissemination of tuberculosis,10 cases pulmonary lymphangitic carcinomatosis,3 cases silicosis,10 cases bronchogenic dissemination of tuberculosis,7 cases bronchioalveolar carcinoma) comfirmed by pathology or clinic were analysed retrospectively.Results:Pulmonary multiple nodules of hemtogenous dissemination of tumor metastasis and of tuberculosis and bronchioalveolar carcinoma were distributed at random.Pulmonary multiple nodules of pulmonary lymphangtic carcinomatosis and silicosis were distributed along with lymph channels;pulmonary multiple nodules of bronchogenic dissemination of tuberculosis had a centrilobular distribution.Conclusion:CT has important value in differentiation of pulmonary multiple nodules.
