Pericardial Diverticulum

Imaging findings

A large fluid-filled lesion in the upper mediastinum that maintains clear continuity with the superior pericardial recess.

Key takeaways

If a cystic-appearing mediastinal lesion shows persistent communication with the pericardial space, it should be classified as a pericardial diverticulum rather than a cyst.
