  Figure 1. CT, cytology, histology, and ECG results from case A. (A) Contrast‐enhanced axial CT scan imaging demonstrating a large irregular mass with infiltration into the right atrial wall and right ventricular myocardium: Panel 1 is an axial view; panel 2 is a coronal view at the level of the red line in A1; panel 3 is a coronal view at the level of the blue line in A1. (B) Lymph node smear showing large blast‐like cells with prominent nucleoli, as well as various lymphoglandular bodies. (C) High power magnification showing positive staining of the tumor cells for CD20. (D) Ventricular tachycardia with normalization of the QRS complex after conversion to sinus rhythm. RA, right atrium; LA, left atrium; RV, right ventricle; LV, left ventricle; Ao, aorta; IVC, inferior vena cava; IVS, superior vena cava; PT, pulmonary trunk.

  Figure 2. Cardiac MRI (four‐chamber view) from patient B. (A) Still frame from cine series showing the tumor (*) expanding from the right atrium toward the tricuspid valve and the right ventricle, and partly obstructing the tricuspid valve. (B) Late gadolinium enhancement showing partial washout in the mass (*), consistent with a malignant tumor.
