Chest X-ray; antero-posterior view. Upper mediastinal widening due to a mediastinal mass (10 cm × 6 cm), more evident on the right side, with polycyclic margins; the angles with the mediastinal contour are obtuse. The hilar vessels cannot be seen through the mass (“hilum overlay sign” absent). The paravertebral line can be recognized. These two findings confirm that this mass is located in the superior-anterior-middle mediastinum. Trachea is deviated laterally to the right side by the mediastinal mass. At the right inferior chest wall subcutaneous tissue mass can be detected
