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
