摘要
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。
Objective To improve the diagnostic accuracy of primary salivary gland-type lung cancer on CT. Methods The CT findings of 13 pathologically proven primary salivary gland-type lung cancers （mucoepidermoid carcinoma, n = 8, adenoid cystic carcinoma, n = 5 ） were retrospectively analyzed. Results Three mucoepidermoid carcinomas were located in the main bronchus, 4 in segmental bronchus, and 1 in peripheral lung. Intrabronchial nodule or mass with smooth or lobulated margin and punctuate or strip calcification （n = 2） was the main CT feature. The tumor showed moderate to significant enhancement after the administration of contrast medium. Three adenoid cystic carcinomas involved trachea, and 2 involved the main and lobular bronchi. The main CT features were diffuse or circumferential irregular thickness of the wall, distorted lumen, and nodule protruding into the lumen, and the longitudinal extent of the tumor was greater than its transverse axis. Conclusion The CT findings of primary salivary gland-type hmg cancer are rather specific and may provide helpful information for the clinical diagnosis and treatment.
