The pericardium seems normal in long and short axis views; however, there was a hyperdynamic heart and dilated right ventricular outflow tract (RVOT) in the short axis view [Figure 1].

The cardiac MRI showed upward rotation in addition to a well-distinguished and extreme levoposition of the heart and the partial absence of the pericardium, especially around the LA and left ventricle (LV), with obvious remnants of the pericardium around the anterior right atrium and basal part of the right ventricle (RV) free wall, followed by a discontinuity of the parietal pericardium around the mid-anterior RV free wall [Figure 2a and b].

The cardiac MRI showed a projection of lung tissue interposed between the aorta and mean pulmonary artery (MPA) [Figure 3].

The aortic arch was right-sided with aberrant origin of the LSCA from the upper descending aorta in addition to a saccular aneurysmal dilatation of the LSCA's origin (Kommerell's diverticulum) resulted compressive effect on posterior wall aspect of esophagus and trachea (vascular ring) [Figure 4].
