肺部空洞性病变的影像学诊断(附75例分析)

目的　提高对肺部空洞病变的诊断及鉴别诊断水平。方法　对本院近 8年来资料完整 ,诊断明确的肺部结核性、癌性及炎症性空洞性病变 75例的胸部X线平片及CT表现进行回顾性分析。结果　肺结核病灶边缘多数光滑 ,密度普遍较高 ,可见斑点状钙化灶 ,可见引流支气管影像 ;肺癌病灶外缘分叶 ,有毛刺 ,洞壁厚 ,内缘凹凸不平 ;肺脓肿空洞内缘光滑整齐 ,可见液平面 ,洞壁厚 ,外缘模糊。结论　明确空洞的密度、整体形态及周围组织的变化是确定诊断和鉴别诊断的关键

Imaging in Diagnosis of the Pulmonary Cavity in 75 Cases

Objective To increase the diagnosis of pulmonary cavity.Methods Retrospectively collected pulmonary cavity 75 cases of our hospital in the late 8 years,and analyzed the features of chest X ray and CT of pulmonary tuberculosis,carcinous and inflammatory cavities.Results The most cases of pulmonary tuberculosis had smooth edge,high density,mottling calcification and communication with bronchia.The pulmonary carcinoma sedg were lobular in shape and had marginal spiculae,thick cavity irregular inside swall.Pulmonary abscess had smooth inside wall liquid in the cavity thick cavity and blurry edge.Conclusion The density total shaope and surrounding change is the key to diagnose pulmonary cavity.
