37-year-old woman with a history of asthma and chronic cough presented with new progressive wheezing and shortness of breath.    Thoracic CT scan demonstrated a paratracheal mass with a narrowing of the distal trachea and proximal main stem bronchi.

Bronchoscopy demonstrated occlusion of the main stem bronchi due to extrinsic compression and an endobronchial polypoid lesion.   A PET/CT scan revealed hypermetabolic paratracheal and peribronchial masses with no distant metastasis.
