AbstractEpipericardial fat necrosis (EFN) is an inflammatory process that occurs in the mediastinal fat surrounding the heart. It is a rare cause of acute chest pain and mimics more ominous clinical conditions such as acute coronary syndrome, aortic dissection, and pulmonary embolism. Clinicians are often not familiar with this condition due to its infrequent occurrence, and traditional textbooks of medicine and cardiology have not covered this topic adequately. In the past, EFN had been managed primarily with thoracotomy and surgical excision. This has changed with advances in imaging techniques and their more frequent utilization. Computed tomography (CT) of the chest is essential for the diagnosis of EFN as it allows for the evaluation of the nature and precise location of the lesion. Magnetic resonance imaging helps to differentiate EFN from other mediastinal fatty lesions such as lipomas or liposarcomas. The clinical presentation of acute chest pain along with CT findings of the encapsulated fatty pericardial lesion is adequate for diagnosis. Our review describes the emerging role of imaging in diagnosis and change in management over the last few years.Copyright © 2021, Zafar et al.
