|
what lobes of the lung make contact with the heart and are where you look for the silhouette sign
*** |
middle lobe (right lung)
lingula (left lung) |
|
|
what can lead to a silhouette sign?
*** |
too much air, too little air, fluid, or no fluid
no air space between the lung and heart (the silhouette sign refers to loss of normal border between structures) |

what is the air bronchogram sign?
|
On a normal CXR, we can visualize the air-filled trachea, mainstem bronchi and initial portions of the lobar bronchi. Further branchings should only be seen with the injection of contrast during a bronchogram. When air can be visualized in the more peripheral intrapulmonary bronchi, this is known as the ‘air-bronchogram sign’. This abnormality is usually caused by an infiltrate/consolidation that surrounds the bronchi.
