The Aorto pulmonary window is a small space between the aortic arch and pulmonary artery that is visible in the lateral chest radiography which contains ligamentum arteriosum, recurrent laryngeal nerve, lymph nodes and fat tissue. Although rare, enlargement of lymph nodes in Aorto pulmonary window can be found in patients with granulomatous diseases (like tuberculosis, sarcoidosis), malignancy and in metastatic diseases.
