摘　　要：目的探讨肺部孤立性结节(solitary pulmonary nodule,SPN)的诊断及鉴别诊断。方法回顾性分析28例SPN的影像表现,所有病例均有常规CT和高分辨率CT(HRCT)资料。结果本组28例SPN的界面影像表现及统计结果,肺癌9例,结核球5例,炎性假瘤2例,腺瘤1例。经抗炎治疗后,病变消失4例,诊断为良性肿瘤。随访2年以上病变无变化的7例。结论界面影像在不同性质的SPN中出现率不同,对肺部孤立性结节有很高的诊断价值。Objective To study the differential diagnosis of sol itary pulmonary nodule （SPN）. Methods Retrospective analysis was used to study the data of conventional CT and high - resolution CT （HRCT） of 28 SPN. Results Phantom performance of SPN in this group of 28 cases, the results indicated that 9 cases were lung cancer, 5 cases were tuberculoma, 2 eases were inflammatory pseudotumor and one ease was adenoma, 4 cases were benign tumor for the l- sions disappeared after anti - inflamnmtory treatment. 7 cases had no changes with the follow - up over two years. Conclusion The occurrence rate of Interface images might be different in all SPNs that should have a high diagnostic value to solitary pulmonary nodules.
