Aortopulmonary stripe
Linea aortopulmonaria
- Synonym: Aortic-pulmonary stripe
Definition
The aortic-pulmonary stripe (aortopulmonary stripe), represents the interface between the left lung and the mediastinum along the main pulmonary artery toward the aortic arch. This edge runs anteriorly to the AP window reflection.
Normal radiographic appearance:
The aortic pulmonary stripe extends from the aortic arch to the level of the left main bronchus, where it usually continues as the border of the left side of the heart. It delineates the anterior margin of the AP window and is normally straight or slightly convex.
Abnormal radiographic appearance:
The normal appearance of this interface may be altered by anterior mediastinal disease such as thyroid masses, thymic tumors and lymphadenopathy .
