摘要：目的 通过16层螺旋CT分析肺孤立性结节与胸膜的关系,以提高对孤立性肺结节的诊断和鉴别诊断.方法 回顾性分析56例已被手术或临床回访证实的肺孤立性结节与邻近胸膜关系的影像学资料.结果 56例中肺癌29例,炎性结节11例,结核球8例,错构瘤4例,转移瘤2例,硬化性血管瘤1例,腺瘤1例.肺孤立性结节与邻近胸膜的改变主要包括胸膜增厚、粘连及胸膜凹陷,其中肺癌病例中有典型胸膜凹陷12例,胸膜呈大范围增厚5例,小范围增厚6例,小范围增厚并有多处粘连6例.11例炎性结节中典型胸膜凹陷2例,胸膜呈大范围增厚5例,小范围增厚并有胸膜粘连4例.结核球有胸膜粘连8例,胸膜小范围增厚1例,1例无胸膜改变.错构瘤、转移瘤、硬化性血管瘤及腺瘤邻近胸膜均无改变.结论 MSCT多层面重建显示肺孤立性结节与胸膜关系对孤立性肺结节诊断和鉴别诊断有很大临床应用价值. Abstract： Objective To analyse the relationship between solitary pulmonary nodules and pleural relationship by 16-slice spiral CT,and to improve the diagnosis of solitary pulmonary nodules and differential diagnosis. Methods A retrospective analysis of 56 cases had been confirmed by surgery or clinical returning to isolate peripheral lung nodules and pleura between adjacent image data. Results In 56 cases, lung cancer of 29 cases, inflammatory nodules of 11 cases, 8 cases of tuberculoma, 4 cases of hamartoma, metastatic tumors, 2 cases of sclerosing hemangioma of a tumor, adenoma in 1 case. Solitary pulmonary nodules and adjacent pleural changes include pleural thickening, adhesions, and pleural indentation. Which lung cancer cases with typical pleural indentation in 12 cases, showed a wide range of pleural thickening in 5 cases,small-scale thickening in 6 cases, small-scale thickening and multiple adhesions in 6 cases. Eleven cases of inflammatory nodules typical pleural indentation, 2 cases showed extensive pleural thickening in 5
