Upper Airway/Trachea
In a normal chest x-ray the mediastinum and diaphragm are visible because of radio density differences (i.e. there is an interface). A loss of normally appearing interfaces usually results from processes in adjacent lung tissue (i.e. consolidation, atelectasis, mass, etc.) The interface loss helps you localize the disease to a specific part of the lung.
Right Upper Lobe – Evaluate
The pathological process can be localized in the right upper lobe when the interface of the SVC and the right superior mediastinum is lost (“Silhouette” sign).
