肺部孤立性炎性病变CT分析

目的：旨在提高对肺部孤立性炎性病变的认识及对该病的正确诊断率。材料与方法：肺部孤立性炎性病变21例，其中4例手术治疗，4例经皮CT引导下肺穿刺活检，13例抗炎治疗后CT随访复查，21例病灶部位均行2mm-5mm薄层CT扫描。结果：1、病变形态呈方形三角形及不规则形13例。2、病灶边缘部分清楚，部分模糊，在肺窗清楚，纵隔窗消失12例。3、病变周边密度较低，呈带状低密度9例。4、抗炎治疗2－10周病灶逐渐吸收11例，2例残留条索阴影。结论：病灶形态呈方形或不规则形，病灶中央密度较高，边缘密度较低且边缘部分清楚，部分模糊，肺窗清楚，纵隔窗消失，对肺部孤立性炎性病变的诊断有很大价值，必要时再行经皮CT引导下肺穿刺活检，能提高肺部孤立性炎性病变的正确诊断率。另外，对基层医院而言，薄层CT扫描尤其必要。

CT Analyse of Solitary Inflammatory Lesion of the Lung

Purpose:To study CT findings of solitary inflammatory lung lesion,and improves CT diagnostic accuracy.Materials and Methods:In 21 cases with solitary inflammatory lung lesion.four cases were treated with surgery,four cases were punctured with CT guided biopsy,the remains cases were treated with anti-inflammatory agents under being followed up with CT.All were scanned with 2mm-5mm thin slice.Results:1.Sign:square,triangle and irregularity.(13 cases).2.Part of margin blurred.(12 cases).3.The density at the edge of the mass was lower than at the central area(9 cases).4.After anti-inflammatory Therapy most lesions gradually reduced in size.(11 cases).Conclusion:Analyzing CT findings helps to diagnose solitary inflammatory lung lesion,and it improves diagnostic accruacy through puncturing with CT guided biopsy necesstiously.To the basic hospital,to scan with 2mm-5mm thin slice is important especially.
