摘　　要：目的分析气管支气管转移瘤(EEM)的CT影像表现,提高对本病的认识.方法回顾性分析6例经病理证实的EEM的CT影像学表现.结果(1)数目:1例为多发,5例为单发,共7枚病灶;(2)部位:3枚病灶位于肺叶支气管,4枚位于肺段及亚段支气管;(3)形态:3枚病灶为肺叶支气管腔内结节,向腔外并沿支气管向远侧生长,4枚肺段支气管病灶表现为分叶状结节或肿块,未见毛刺及胸膜牵拉征,7枚病灶均伴有指套征;(4)密度及增强:6枚病灶密度均匀,1枚病灶伴沙粒样钙化,病灶强化特征与原发病类似;(5)伴随征象:1例伴发阻塞性肺炎及阻塞性肺不张,1例伴发支气管黏液栓,1例伴有同侧胸腔积液,6例患者均未见纵隔及肺门肿大淋巴结.结论EEM表现为单发或多发肺叶、段支气管腔内外结节或肿块,分叶状,沿支气管长轴呈指套样生长,无毛刺及胸膜牵拉征,增强表现与原发肿瘤类似,纵隔及肺门淋巴结肿大少见.Objective To analyze CT findings of endotracheal/endobronchial metastases(EEM),to improve the understanding of the disease.Methods CT imaging findings of 6 patients with pathologically confirmed EEM were analyzed retrospectively.Results(1)Number:l case was double lesions,5 cases were single lesion,a total of 7 lesions;(2)Location:3 lesions were located in the lobe bronchi,4 lesions were located in the segmental and sub segmental bronchi;(3)Morphology:3 lesions were intraluminal nodules in the lobe bronchi which grew to the outside of the tube and along the bronchus.4 bronchial lesions showed lobular nodules or masses without burrs and pleural traction.All the lesions were accompanied by finger signs;(4)Density and enhancement:6 lesions were uniform density,1 lesion with sand-like calcification;on the other hand the enhancement features of lesions were similar to the primary tumor;(5)Concomitant signs:1 case with obstructive pneumonia and obstructive atelectasis,1 case with bronchial mucus plugging,1 case with ipsilateral pleural effusion,and all the 6 cases without lymphadenopathy in the mediastinum and hilum of lung.Conclusion EEM is.characterized by single or multiple nodules or masses which are in the lung bronchus and segmental bronchus and sometimes outside of the cavity.It is lobulated and grows as the shape of finger sleeve along the long axis of the bronchus.There is no burr and pleural traction and its enhanced performance is similar to that of the primary tumor.Lymphadenopathy in the mediastinum and hilum of lung is rare.
