Multimodality Imaging in the Evaluation of Cardiovascular Manifestations of Malignancy

Figure 7

Thrombus. A coronal maximum intensity projection image from a contrast MDCT study demonstrates multiple pulmonary emboli ((a), white arrows). On the same study the possibility of a right atrial mass was raised ((b), white arrow), although it was uncertain whether this was real or simply an appearance due to incomplete mixing of opacified SVC blood with unopacified IVC blood. Cine CMR demonstrates that the mass is clearly real ((c), black arrow). Further characterization by CMR demonstrates that the mass is low signal on T1 weighted images ((d), white arrow) and remains low signal following gadolinium administration ((e), white arrow). The appearances and clinical presentation were entirely consistent with right atrial thrombus. The mass disappeared with subsequent anticoagulation.
