(a, b) CTPA showed an irregular filling defect in the right atrium. The CMR scan acquired 2 months after the CTPA of the same patient. The still frames from SSFP CMR cine 4-chamber (c) and the corresponding late gadolinium image (d) with the short-axis (e) image showing a large ovoid mass adjacent to the right atrium and attached to the right atrioventricular groove, invading into the right atrium. There are also two additional pericardial masses on the left lateral side, not invading into the myocardium, which showed heterogeneous, mild patchy gadolinium uptake on late gadolinium imaging (f). CTPA, CT pulmonary angiogram; CMR, cardiac magnetic resonance; SSFP, steady-state free precession.
