Fetal echocardiography [Figure 1a] demonstrated a 16 x 19 mm intracardiac right atrial mass without hemodynamic compromise. Preoperative cardiac imaging included a transthoracic echocardiogram [Figure 1b] and MRI [Figure 2].

Preoperative cardiac imaging included a transthoracic echocardiogram [Figure 1b] and MRI [Figure 2].
T2-weighted MRI shows a hyper-intense 1.9 x 1.4 x 1.4 cm mass arising from the infero-medial wall of the right atrium interposed between the inferior vena cava and tricuspid valve. The mass demonstrated a focal area of high attenuation in its lateral portion on pre-contrast T1-weighted imaging, suggesting a hemorrhagic or proteinaceous component

The tumor was located between the coronary sinus, inferior vena cava, and foramen ovale with a portion attached to the right atrial free wall just above the inferior vena cava [Figure 3a]. The 2 x 2 cm tumor [Figure 3b] was sharply resected removing a portion of the right atrial wall and staying clear of the coronary sinus.
