aortopulmonary window; Definition :
A congenital anomaly in which there is abnormal communication between the ascending
aorta and pulmonary artery just above the semilunar valves. [MeSH] Anatomy.—The aortopulmonary
window is the mediastinal region bounded anteriorly by the ascending aorta, posteriorly
by the descending aorta, cranially by the aortic arch, inferiorly by the left pulmonary
artery, medially by the ligamentum arteriosum, and laterally by the pleura and left
lung (15,16). Radiographs and CT scans.—Focal concavity in the left mediastinal border
below the aorta and above the left pulmonary artery can be seen on a frontal radiograph
(Fig 5). Its appearance may be modified by tortuosity of the aorta. The aortopulmonary
window is a common site of lymphadenopathy in a variety of inflammatory and neoplastic
diseases. [Fleischner Society]; Image(s) :
