AbstractEpipericardial fat necrosis is an uncommon benign entity of unknown cause, with only 20 cases reported in the English-language literature. It should be remembered as a possible diagnosis in a person who presents with acute pleuritic chest pain and paracardiac density or pleural effusion on chest radiography (X-ray). The computed tomography (CT) or surgical approach allows the final diagnosis and characterization. The authors describe a case of a 48-year-old woman, admitted to our department because of complaints of fatigue, cough and sudden pleuritic pain on thoracic left side. The chest X-ray showed mild/moderate left pleural effusion and CT scan revealed local slight thickening of pericardium and epipericardial fat, surrounded by thick rim of higher density in the left cardiophrenic space. This made the diagnosis of epipericardial fat necrosis. During hospitalization the patient remained stable and was discharged home with symptomatic relieve therapy. Because of benign, self-limited nature of this entity, only conservative treatment is indicated.
