FIGURE 1. Erect postero‐anterior chest X‐ray showing a bulge on the right side of the heart (arrow)

FIGURE 2. Transthoracic echocardiography showing an extracardiac cyst with spontaneous echo contrast adjacent to and compressing the right atrium (white arrow). LA, Left atrium; LV, Left Ventricle; RV, Right Ventricle

FIGURE 3. Transesophageal echocardiogram showing an extracardiac cyst with dense spontaneous echo contrast (panel A, red arrows) and its corresponding three‐dimensional image (panel B, green arrow)

FIGURE 4. Cardiac CT with contrast showing a well‐defined, cystic globular‐like mass adjacent to the right atrium (Panel A, black arrow). Three‐dimensional reconstruction of cardiac CT images shows a giant right coronary artery aneurysm (Panel B, white arrow)

FIGURE 5. CT angiogram of the aorta and its branches showing fusiform dilatation of the LMCA (panel A, yellow arrow) and a large saccular aneurismal dilatation of the proximal RCA (panel B, red arrow) compressing the right atrium (panel B, blue arrow)
