title: Acute Aortic Dissection Extending Into the Lung.
abstract: The radiologic manifestations of ruptured acute aortic dissection, Stanford type A aortic dissection, DeBakey type 1 can present in different radiographic scenarios with devastating outcomes. Here, we present a rare case of a 70-year-old man who presented to the emergency department with chest pain radiating to the back. A chest computed tomography scan showed a Stanford type A, DeBakey type 1, acute aortic dissection ruptured into the aortopulmonary window and stenosing the pulmonary trunk, both main pulmonary arteries, and dissecting the bronchovascular sheaths and flow into the pulmonary interstitium, causing pulmonary interstitial hemorrhage. The patient underwent emergent ascending aorta replacement with hemiarch replacement with circulatory arrest. The postoperative course was unremarkable.
