Posterior mediastinal mass

  • A large round area of increased density indicates the presence of a soft tissue mass in the region of the left hilum
  • The left heart border (adjacent to the anterior mediastinum) remains well defined
  • Vessels of the left hilum area – including the left pulmonary artery (middle mediastinum) – also remain well defined
  • Obscuration of the descending aorta (posterior mediastinum) confirms the mass is located posteriorly
