Presence of a right paratracheal mass on the PA view, not visualized on the lateral view, with associated tracheal deviation to the right. No evidence of airway obstruction. A CT scan is recommended for further evaluation to rule out underlying mass or adenopathy. Differential considerations include vascular anomalies or an enlarged thyroid. There is no post-obstructive pneumonia, and the lungs appear clear.
