Mediastinum - Masses On the chest film there is a mass that has obtuse angles with the mediastinum, so it is a mediastinal mass. The hilar vessels are seen through this mass, so it does not arise from the hilum and probably will arise from the anterior mediastinum.The anterior location was confirmed on a CT.hen there is a mediastinal mass and you still can see the hilar vessels through this mass, then you know the mass does not arise from the hilum. This is known as the hilum overlay sign. Because of the geometry of the mediastinum most of these masses will be located in the anterior mediastinum.
