Transesophageal echocardiographic imaging-bicaval view-confirmed a 2.5 × 1.5 round solitary lesion with distinctive borders attached in the SVC, protruding into the right atrium (Thick arrow). The echo lucent area-marked with the thin arrow-most probably presents an abscess of the interatrial septum (A, B). Flow from the superior vena cava was obstructed (B).
