Abstract： 目的研究中央型肺癌早期CT表现及其病理学基础,并评价CT在鉴别诊断中的作用.方法对17例病理证实的早期中央型肺癌及10例类似中央型肺癌的良性病变进行分析,CT采用SR 7000及(或)Lightspeed Plus扫描机,3.0或1.5 mm层厚薄层扫描,将CT表现与支气管镜及手术病理组织学表现对照.结果 17例病变CT均显示,3例显示为局部支气管管壁增厚、管腔内壁不规则,支气管镜显示黏膜表面粗糙、红肿. 14例显示管腔狭窄、闭塞,其中4例合并亚段支气管黏液栓,10例合并阻塞性肺炎或肺不张,支气管镜表现为腔内息肉样病灶.病理组织学显示1例累及黏膜,5例累及黏膜下,11例侵犯支气管软骨层.10例良性病变中,CT检查怀疑6例恶性病变,4例不排除恶性,支气管镜检查5例显示内壁不均匀增厚、粗糙,2例管腔内凝血块,1例管腔内结节,2例未见异常.结论薄层CT扫描能可靠地显示支气管细微病变,是诊断早期中央型肺癌非常有用的方法.
