Presence of a right paratracheal mass on the PA view, not visualized on the lateral view. There is associated tracheal deviation to the right without evidence of obstruction. A CT scan is recommended for further evaluation to rule out underlying mass or adenopathy. Differential diagnosis includes vascular anomalies or an enlarged thyroid. No signs of post-obstructive pneumonia are noted, and the lungs appear clear.
