The purpose of this essay is to illustrate the CT findings of variable benign tumors of the tracheobronchial tree and to correlate the CT and pathologic findings in 17 patients.
The tracheal tumors were eccentric, well-defined, polypoid masses in all cases. The endobronchial tumors were masses confined within the bronchus in all cases, and atelectasis or pneumonia of the distal parenchyma was frequently associated. Of the six hamartomas, one was a fatty mass, and two were nodules with calcification. The others were soft-tissue-density nodules. The lipomas manifested as fat density on CT scans in both cases. The other benign tumors were low-attenuating, soft-tissue-density masses without characteristic findings on CT scans.
本文旨在阐述气管支气管树各种良性肿瘤的CT表现，并将17例患者的CT与病理结果进行对比。
所有病例中气管肿瘤均为偏心性、边界清晰的息肉样肿块。所有病例中支气管内肿瘤均为局限于支气管内的肿块，常伴有远端实质的肺不张或肺炎。6例错构瘤中，1例为脂肪性肿块，2例为钙化结节，其余为软组织密度结节。2例脂肪瘤在CT扫描上均表现为脂肪密度。其他良性肿瘤为低密度软组织密度肿块，CT扫描无特征性表现。
