Abstract:
This review focuses on 2 fat-containing entities in the mediastinum that may raise a diagnostic challenge: Morgagni's hernia and Epipericardial (mediastinal) fat necrosis. Familiarity with the typical imaging findings of these 2 entities is vital for the radiologist to recognize and accurately characterize unusual mediastinal pathological conditions.
