原发涎腺型肺癌的CT诊断

目的总结原发涎腺型肺癌的cT表现特点，以提高其影像学诊断准确率。方法回顾性分析经病理证实的13例原发涎腺型肺癌（黏液表皮样癌8例，腺样囊性癌5例）的cT表现。结果8例黏液表皮样癌中，3例位于主支气管内，4例位于段支气管内，I例为周围型，位于肺内。其主要CT表现为：支气管内光滑卵圆形或分叶状结节或肿块，可见点状或条状钙化，增强后中等度至显著强化。5例腺样囊腺癌中，3例侵及气管，2例侵及主支气管及叶支气管。其主要cT表现为：气管或支气管壁弥漫或环形不规则增厚，管腔变形，可见结节突出于管腔内，肿瘤长径大于横径。结论原发涎腺型肺癌的CT表现具有一定特征，对于临床诊治有一定帮助。
