A Case of Thymic Carcinoma Misdiagnosed as Epipericardial Fat Necrosis / 대한내과학회지

ABSTRACT

Epipericardial fat necrosis (EPFN) is an uncommon benign condition of unknown etiology. It presents as an unexplained acute severe pleuritic chest pain that is associated with the presence of a well-defined juxtacardiac mass usually located in or near the cardiophrenic angle. Although its typical clinical manifestations and chest computed tomography findings might lead to successful diagnosis of this rare disease, an unusual mass location such as the anterosuperior mediastinum should be considered and biopsies should be performed. We herein report a case of thymic carcinoma that was suspected initially to be EPFN.
