A 39-year-old man presented in the emergency department (ED) with shortness of breath. Physical examination was unremarkable besides hyperventilation with an oxygen saturation of 100%. His symptoms subsided spontaneously in the ED. However, the chest x-ray (A to C) demonstrated a coincidental right paracardiac mass on the posteroanterior view and presented as a “real heart sign” on the lateral view, suggestive of a pericardial cyst. On echocardiography and cardiac magnetic resonance imaging (MRI) (D, Online Video 1), the free lateral wall of the right atrium and tricuspid annulus were compressed by a fluid-filled mass, without hemodynamic consequences. On MRI, malignancy could not be excluded. Positron emission tomography/computed tomography excluded malignant disease (E). For prevention of hemodynamic consequences for the right atrium and ventricle, the mass was successfully drained and removed during video-assisted thoracoscopic surgery (F). Pathological examination confirmed the diagnosis of a pericardial cyst.
