Anterior mediastinal mass - Thymoma

  • The mediastinal contours are bulging due to a large mass – in this case a thymoma
  • It is possible to determine that this mass is located anteriorly in the mediastinum
  • The aortic knuckle (mid mediastinum) and both the azygo-oesophageal and descending aorta lines (posterior mediastinum) are clearly visible and so the mass cannot be located adjacent to these structures
