肺部单发空洞病变的CT诊断及鉴别诊断

CT Diagnosis and Differential Diagnosis of the Alone Pulmonary Cavity

目的:提高对肺部常见空洞病变的诊断及鉴别诊断水平。方法:本院4年来诊断明确的单发空洞性病变70例的胸部CT表现进行回顾性分析。结果:肺结核36例,肺癌14例,肺脓肿18例,肺转移瘤1例,真菌感染1例。肺结核空洞内缘多较光滑,密度普遍较高,周围卫星灶常见;肺癌多表现为病灶外形分叶,壁厚、内缘凹凸不平,壁结节、毛刺、胸膜凹陷、血管集束等恶性征象;肺脓肿空洞内缘多较光滑,可见液平面,洞壁厚,外缘模糊。结论:肺内单发空洞病变的大小、洞壁的厚度、空洞内外缘的表现、洞内及周围的异常形态等,是诊断和鉴别诊断的关键。

Objective:To increase the diagnosis and differential diagnosis level of common alone pulmonary cavity.Methods:Retrospectively collect pulmonary caviy 70 cases of our hospital in thelate 4 years,and analyzed the features of chest CT.Results:Pulmonarytuberculosis 36 cases,pulmonary carcinous 14 cases and pulmonary abscess 18 cases,pulmonary metastasis 1 cases,fungous infection 1 cases.The mostcases of pulmonary tuberculosis had smooth inner margin,highdensity,surrounding satellite common.The pulmonary carcinoma seg inshape,thick cavity,inside marginal rugosity,pariesnodus,sentus,membrana pleuralis introcession.Pulmonary abscess badsmooth inside margin,fluid level,thick cavity and blurry of outermargin.Conclusion:The size of alone pulmonary cavity,wallthickness,exterior and interior of cavity to show,cavity inside andsurrounding abnor appearance,key to diagnosis and different diagnosis.
