Silhouette Sign

•  The loss of the lung/soft tissue interface due to the presence of fluid in the normally air-filled lung
•  If an intrathoracic opacity is in anatomic contact with a border, then the opacity will obscure that 
border
•  Commonly seen with the borders of the heart, aorta, chest wall, and diaphragm
