Complete obstruction of the right main bronchus from the level of the carina by a soft tissue density within the lumen. The trachea is deviated to the right. Subsequent collapse of the right lung with right hemithorax volume loss. The right lower lobe is "drowned" with prominent mucous plugging, however, patent pulmonary veins and arteries. The right upper lobe pulmonary artery is truncated with reduced perfusion to the right upper lobe. Impression of multiple right sided pulmonary metastases - difficult to clearly delineate amongst collapsed lung. A 2.8 x 2.1 x 5.4 cm, right paratracheal lymph node is noted.The left lung is clear.
Conclusion:
Obstruction of the right main bronchus by a soft tissue mass resulting in airless "drowned" right lung with subsequent volume loss and mediastinal shift. Impression of multiple pulmonary metastases. Right paratracheal lymphadenopathy. Right pleural effusion.
