Multidetector Computed Tomography (MDCT) multiplanar reconstruction (MPR) image on oblique coronal plane demonstrates an intrapericardial grossly round mass (arrows) between the left atrium and the left ventricle. The mass impresses the posterior wall of the left ventricle and the atrium. In this early arterial phase the center of the mass is not yet opacified. Pericardial effusion coexists and surrounds the mass.
