Posterior pericardial recess

Last revised by Arlene Campos on 12 Jan 2024

The posterior pericardial recess is one of the pericardial recesses forming a small space within the pericardium. It arises from the superior margin of the oblique pericardial sinus, posterior to the right pulmonary artery and medial to the bronchus intermedius.

Clinical significance

It may mimic mediastinal lymphadenopathy or a bronchogenic cyst.
