case_images: Preoperative enhanced computed tomography. (a) Two bundles of masses in the right atrium. (b) Irregular marginated tumor mass located in the mediastinum, superior vena cava, and bilateral brachiocephalic veins.

case_images: fig1-2050313X221138652
case_images: Contrast-enhanced computed tomography revealed irregular marginated tumors in the mediastinum, SVC, RA, and left and right brachiocephalic veins (Figure 1(a) and (b)).
case_images: Operative findings. (a) Two bundles of masses in the right atrium. (b) The two separate polytetrafluoroethylene grafts were anastomosed to the right atrium reconstructed by bovine pericardium.

case_images: fig2-2050313X221138652
case_images: The SVC and RA were incised, and two bundles of masses were observed in the free wall of the RA (Figure 2(a)). RA was reconstructed with bovine pericardium, and the bilateral brachiocephalic grafts were separately anastomosed to RA (Figure 2(b)).
