Abstract
|
|
|
|
Endotracheal/endobronchial metastasis, which is from either primary bronchogenic carcinoma or a tumor of non-pulmonary origin, is a rare but life-threatening condition. Among the different locations in the tracheobronchial tree, the trachea is an extremely rare location for metastasis from extrapulmonary tumor. To the best of our knowledge, endotracheal metastasis that was clearly visualized by F-18 FDG PET/CT has not been previously reported. We herein report on a patient with a FDG-avid endotracheal eccentric mass that was confirmed as metastasis from rectal cancer.
