实变型细支气管肺泡癌与肺炎的CT鉴别诊断

目的:探讨实变型细支气管肺泡癌与肺炎的CT特征以及哪些征象对于鉴别二者更有帮助。方法:回顾性分析26例经病理证实的实变型细支气管肺泡癌和36例肺炎的CT表现,包括病变的分布、密度、假囊征、空气支气管征、枯树枝征、铺路石征、实变边缘磨玻璃密度影、独立存在的磨玻璃密度影、实变跨肺叶分布、实变肺叶体积增大和叶间裂膨隆、肺不张、CT血管造影征、共存结节、纵隔淋巴结、胸水以及胸膜肥厚。结果:具有统计学意义(p0.01)的CT表现包括病变的密度、假囊征、枯树枝征、铺路石征、实变边缘磨玻璃密度影、实变跨肺叶分布、实变肺叶叶间裂膨隆以及共存结节。结论:患者肺部出现低密度实变,并具有假囊征、枯树枝征、铺路石征、实变边缘磨玻璃密度影、实变跨肺叶分布、实变肺叶叶间裂膨隆、CT血管造影征和共存结节,提示实变型细支气管肺泡癌的可能性。

CT Differentiation of Consolidative Bronchioloalveolar Carcinoma and Pneumonia

Objective:To investigate the value of CT image findings in differentiating diagnosis of bronchioloalveolar carcinoma(BAC) and pneumonia.Methods:Twenty-six patients of bronchioloalveolar carcinoma and thirty-six patients of pneumonia underwent chest scans with Siemens 16-slice CT.Image findings of consolidation,pseudocavitation,air bronchogram sign,leafless tree sign,crazy paving,ground-glass opacities,consolidation crossing lobe,bulging of fissure,atelectasis,CT angiogram sign,coexist nodule,lymph node,pleu...
