Last revised by Henry Knipe on 10 Apr 2023

The posterior superior aortic recess, also known as the superior pericardial recess or the superior sinus, is one of the variable invaginations of the superior aortic recess and is located posterior to the ascending aorta. It may mimic mediastinal lymphadenopathy or a bronchogenic cyst.
