Epicardial Fat – Case report

The arrow indicates a space anterior to the right ventricle, which is of mixed echogenicity. This is a typical finding in individuals with epicardial fat. Epicardial fat is generally seen in between the right ventricular wall and chest wall. It is an area that is almost echo-free and moves with the right ventricle. CT scan of the same patient clearly delineates this structure as epicardial fat due to its low Hounsfield units (dark appearance). A pericardial effusion is usually echo-free, although a pericardial hematoma can have mixed echogenicity
