Epicardial fat necrosis: an uncommon etiology of chest pain.

Epicardial fat necrosis (EFN) is a rare cause of severe chest pain. We present a case of EFN successfully treated conservatively. With the advent of computed tomography and magnetic resonance imaging, the diagnosis can be made more precisely, avoiding the need for surgical intervention. We review the clinical characteristics, pathogenesis and treatment options of EFN.
