中文摘要	目的探讨孤立性肺转移瘤(SPM)的CT表现,以提高对SPM的CT诊断水平.方法对21例经病理证实的SPM的CT表现进行回顾性分析. 结果①病灶分布: 21例SPM中位于左肺10例(47.6%),右肺11例(52.4%); 双肺上叶(不含左上叶舌段)3例(14.3%),右中叶及左上叶舌段5例(23.8%),双肺下叶13例(61.9%); 位于肺野外1/3带者14例(66.7%), 中1/3者 5例(23.8%),内1/3者 2例(9.5%). ②大小:<3 cm者17例(81.0%),>3 cm者4例(19.0%).③形态、边缘:15例(71.4%)呈圆形或椭圆形且表面光滑,界面清楚,6例(28.6%)呈不规则形并分别或同时见分叶征(3例)、毛刺征(2例)、胸膜凹陷征、血管集束征、晕环征(各1例).④密度:病灶呈均匀软组织密度16例(76.2%),内见钙化灶2例,空洞1例,低密度坏死区2例.⑤本组病例均未见SPM侵犯临近支气管.结论 SPM的CT表现具有一些特点,但其诊断与鉴别诊断需CT表现紧密结合临床和病理才能得出正确结论.
英文摘要	Objective To explore the CT appearances of solitary pulmonary melaslases( SPM ) in order to improve the level of CT diagnosis of SPM. Methods The CT findings of 21 cases with SPM proved by pathology were analyzed retrospectively . Results I. The distribution of lesions:in 21 oases with SPM were; 10 ( 47. 6% ) niduses in left lung , 11 ( 52.4% ) lung in right ;3 (14.3% ) in bilateral superior lobuses ( excluding segmentum lingulare ) ,5 ( 23.8% ) in lobus medius and segmentura lingulare, 13 ( 61.9% ) in inferior lobuses; 14(66.7% Jin external 1/3 of lung field,5 (23. 8% ) in middle 1/3 and 2(9.5% ) in inleriorl/3; 2. The diameter of lesions werejd <3 cm (17oases,81. 0% ) ,d>3 cm(4,19.0% ). 3.The shape and the margin of lesions were: circular or ellipse niduses with smooth surface and clear lumor-lung interface in 15 ( 71.4% ) .irregular - shaped niduses in 6 ( 28.6% ) , with lobulalion sign in 3 , spiculae in 2 , pleural indentation,bronchovascular bundles and halo in 1 respectively ; 4. The density of lesions were;Uniform soli tissular density in 16 cases (76.2% ) ,calcification in 2,cavity in 1 and necrotic area in 2; 5. In all 21 cases.it was not found that SPM invaded bronchi nearby . Conclusion SPM has some certain characterizes on CT,but only by combining CT appearances with clinic and pathology, its correct diagnosis can be done.
