title: Tracheal metastasis of lung cancer: CT findings in six patients.
abstract: OBJECTIVE
  Our objective was to assess CT findings of tracheal metastasis of lung cancer.
  
  
  CONCLUSIONS
  Tracheal metastasis of primary non-small cell lung cancer manifested as an endotracheal nodule or eccentric wall thickening of the trachea, showing contrast enhancement with a predilection for the upper trachea on CT. During postoperative evaluation of patients with surgically resected lung cancer, the possibility of tracheal metastasis of lung cancer should be suggested when an endotracheal nodule or eccentric wall thickening is present on CT.
