The latest CT imaging indicated enlargement of the mass. Transthoracic echocardiography showed that a mobile mass in contact with the septum was present in the right atria, and a very bright region suggesting partial calcification was noted (Figure 1A and online-only Data Supplement). On nongated chest contrast CT, a low-intensity 26×20-mm region without enhancement and with partial calcification was present in the right atrium (Figure 1B and online-only Data Supplement); noncontrast MRI of the chest showed a round lesion with a diameter of approximately 26 mm and a clear boundary in contact with the septum. The inner region of the mass showed a slight high intensity on T1-weighted imaging (Figure 2A and online-only Data Supplement) and a low intensity …
