a Pre-contrast gated CT angiogram shows a small outpouching from the right ventricle apex into the pericardial space, connected through a small neck to the ventricle. b Post-contrast gated CT angiogram shows a small outpouching from the right ventricle apex into the pericardial space, connected through a small neck to the ventricle. c Reconstructed gated CT image shows a small outpouching from the right ventricle apex into the pericardial space, connected through a small neck to the ventricle with minimal pericardial effusion adjacent to the right ventricle
