Epipericardial fat necrosis.

چکیده
A 57-year-old man with no cardiovascular risk factors or other disease history of interest developed acute chest pain without clear signs of angina. He came to the emergency department, where the results of the electrocardiogram and an initial test for markers of myocardial injury were normal. We performed cardiac computed tomography, which ruled out the existence of coronary artery lesions. However, images of the fat at the left cardiophrenic angle (Figure) revealed a poorly defined increase in the density (arrows), with a central zone of the same density as that of the mediastinal fat (asterisk). Within the lesion, there was a modest increase in density in the form of fine filaments. These findings are typical of pericardial fat necrosis. This is an uncommon, benign condition that presents clinically with acute onset chest pain in previously healthy individuals. The etiology is unknown, and it has the same anatomic pathological features as fat necrosis at other sites (breast, epiploic appendages). The pain is self-limiting and lasts for only a few days; thus, symptomatic treatment is sufficient. Acute onset chest pain is a common cause for emergency department visits, and the etiology is sometimes difficult to determine. In this context, cardiac computed tomography is becoming established as a rapid and widely available technique that provides a great amount of information on both cardiac and extracardiac structures. Although this technique may not provide images of coronary artery lesions, the examination of the remaining structures is also important. In some cases, it will enable us to establish the etiology, initiate the most adequate treatment, and avoid unnecessary additional studies. Figure.

Epipericardial fat necrosis: an unusual cause of chest pain
Epipericardial fat necrosis is a rare, benign, and self-limited cause of acute chest pain, with only 35 cases reported in the literature.(1,2) It presents as new-onset pleuritic chest pain in otherwise healthy patients, and, therefore, it is an important differential diagnosis for acute chest pain in this group of individuals. The pathophysiology has been labeled as idiopathic or related to an ...
متن کاملEpipericardial fat necrosis – a rare cause of pleuritic chest pain: case report and review of the literature
Epipericardial fat necrosis (EPFN) is an uncommon cause of chest pain. Typically manifesting as severe acute chest pain, EPFN can be mistaken for a serious disorder, such as pulmonary embolism or myocardial infarction. We report a case of EPFN, diagnosed tentatively based on clinical and radiographic findings, with documented resolution of the lesion on chest CT. According to our literature sea...

Mediastinal fat necrosis (MFN) or epipericardial fat necrosis, as it is commonly referred to in the literature, is a rare self-limiting cause of chest pain of unclear etiology. MFN affects previously healthy individuals who present with acute pleuritic chest pain. Characteristic computed tomography (CT) findings include a fat attenuation lesion with intrinsic and surrounding increased attenuati...
متن کاملAcute Chest Pain Related to Pericardial Fat Necrosis
An otherwise healthy 56-year-old woman (BMI, 31 kg/m) presented to our emergency department with acute nonradiating left-sided chest pain. She had no associated dyspnea, fever, or other clinical findings. An electrocardiogram and serum troponin level were unremarkable. Nonenhanced computed tomography (CT) of the chest (Figure 1) showed a left anterior low-attenuation (−80HU) pericardial mass wi...
