Abstract
BACKGROUND: Endotracheal and endobronchial metastases (EEM) is a rare manifestation in primary lung cancer. It has not yet been reported in Chinese literatures. The aim of this study was to summarize and analyze the clinical feature of lung cancer with EEM.Entities:

1鳞癌患者发生EEM的胸部影像和支气管镜表现(表 1中患者1)。A:PET/CT示右肺门不规则软组织密度肿物,FDG摄取明显增高,伴右中下叶肺不张;左肺下叶背段支气管开口处FDG摄取轻度增高;B:支气管镜示右肺下叶支气管新生物伴出血(箭头);C:左肺下叶背段支气管开口处可见局限性异常白色黏膜隆起(箭头)
Chest radiographic and bronchoscopic images in a patient with squamous lung cancer and EEM (patient 1 in Tab 1). A: PET/CT showing irregular mass in the right hilum, with marked FDG uptake; B: Bronchoscopic examination showing an endobronchial tumor with bleeding in the right lower lobe (arrow); C: A white bulge with distinct border at the orifice of apical segmental bronchus in left lower lobe (arrow). FDG: F-18 fluorodeoxyglucose; PET/CT: positron emission tomography/computed tomography
2小细胞肺癌患者发生EEM的胸部影像和支气管镜表现(表 1中患者6)。A:CT示左肺门肿块(星号);B、C、D:支气管镜示左肺上叶可见新生物致管腔完全闭塞(B箭头),气管上段左外侧壁息肉样病变(C箭头),左主支气管入口左侧壁息肉样病变(D箭头);E、F:回顾肺CT分别可见气管和左主支气管局部管壁增厚(箭头)
Chest radiographic and bronchoscopic images in a patient with SCLC and EEM (patient 6 in Tab 1). A: Chest CT showing an irregular mass in the left perihilar lung; B, C, D: Bronchoscopy revealing the left upper lobe bronchus was occluded completely by an endobronchial neoplasm (B, arrow), one polypoid lesion located in the left lateral wall of the upper trachea (C, arrow), and the other polypoid lesion in the medial wall of the left main bronchus inlet (D, arrow); E, F: Review of his chest CT showing eccentric thickening of the upper trachea (E, arrow) and the left main bronchus (F, arrow)
