Figure 1: (a) Volume-rendered MSCT image showing the site of the lesion centered on the AV groove, splaying the right atrium (RA) and right ventricle (RV) and slightly compressing them and the origin of the main pulmonary artery (PA). It also demonstrates the right coronary artery (RCA) originating from the aorta (AO) and passing into the site of the lesion without alteration of its course. (b) MSCT image of the heart in the axial plane after contrast administration showing the partially heterogenous hypodense lesion (L) involving the anterior mediastinal region, splaying the right atrium (RA) and right ventricle (RV), with the right coronary artery (RCA) seen arising from the aorta (AO) and passing anteriorly traversing the lesion. It also shows that the lesion is deep within the pericardium (P) with pericardial effusion
