Aortopulmonary space

(Redirected from Aortic window)

The aortopulmonary space is a small space between the aortic arch and the pulmonary artery. It contains the ligamentum arteriosum, the recurrent laryngeal nerve, lymph nodes, and fatty tissue.[1] The space is bounded anteriorly by the ascending aorta, posteriorly by the descending aorta, medially by the left main bronchus, and laterally by mediastinal pleura.

On a lateral chest radiograph, the aortopulmonary space is normally seen as the "aortopulmonary window".[1]

The presence of radiodensity in this space on radiography may indicate lymphadenopathy.[2]
