摘　　要：目的:分析肺部炎性假瘤的高分辨率CT影像学表现极其鉴别诊断的价值。方法:收集2012年4月-2015年4月我院收治的59例经手术病理检查证实为肺部炎性假瘤的患者为病例组,并于同一时期随机选取80例周围型肺癌患者为对照组。比较两组患者的高分辨率CT影像学特征,并分析各种影像学特征与肺部炎性假瘤的关系。结果:病例组刀切征、桃尖征及延迟期持续强化的发生率高于对照组,分叶征的发生率低于对照组(均P<0.05)。多因素Spearman的秩相关分析发现,刀切征、桃尖征及延迟期持续强化与肺部炎性假瘤诊断呈正相关关系(r=0.738,0.829,0.763,均P<0.05),分叶征与肺部炎性假瘤的诊断呈负相关关系(r=-0.791,P<0.05)。结论:CT影像学表现中的刀切征、分叶征、桃尖征及延迟期持续强化对肺部炎性假瘤具有较高的鉴别诊断价值,可作为临床辅助诊断肺部炎性假瘤的重要影像学资料。Objective：To explore the high resolution CT imaging signs of pulmonary inflammatory pseudotumor and their differential diagnosis value.Methods：Collected 59 patients with pulmonary inflammatory pseudotumor who were diagnosed by pathological examination as pseudotumor group,and selected 80 patients with peripheral lung cancer as control group randomly at the same time.Compared the high resolution CT imagning signs in two groups,and analyzed their correlation with pulmonary inflammatory pseudotumor.Results：The incidence of knife cut sign,peach tip sign and delayed reinforcement in pseudotumor group were higher than control group,the incidence of lobulation sign in pseudotumor group was lower than control group（all P0.05）.Multivariate Spearman rank correlation analysis found that knife cut sign,peach tip sign and delayed reinforcement were positively correlated with pulmonary inflammatory pseudotumor（r=0.738,0.829,0.763,all P0.05）,and lobulation sign was negatively correlated with pulmonary inflammatory pseudotumor（r=-0.791,P0.05）.Conclusion：There is a high differential diagnosis value of knife cut sign,lobulation sign,peach tip sign and delayed reinforcement of CT imaging signs for pulmonary inflammatory pseudotumor,which can be an important imaging data in the auxiliary diagnosis of pulmonary inflammatory pseudotumor.
