Two-dimensional transthoracic echocardiography with color Doppler showed a mass of approximately 5.6 cm x 2.2 cm, attached to the right atrium [Figure 1] with mild pericardial effusion and global hypokinesia of left ventricle.
18F-fluoro-deoxyglucose (FDG) contrast enhanced positron emission tomography-computed tomography (PET-CT) images. (a) Whole body maximum intensity projection images showing intense FDG uptake in cardiac mass with multiple FDG avid metastases, (b) transaxial CT and corresponding fused PET-CT, (c) coronal CT and corresponding fused PET-CT sectional images showing very high FDG uptake in a hypodense mass in right atrium (SUVmax 19.2) with associated pericardial infiltration and minimal pericardial effusion

PET-CT whole body study for work up. PET-CT showed a well-defined heterogeneously enhancing hypodense mass in the right atrium with intense FDG uptake (SUVma x 19.2) along with pericardial infiltration and minimal pericardial effusion [Figure 2].
18F-fluoro-deoxyglucose (FDG) contrast enhanced positron emission tomography-computed tomography (PET-CT) images. (a) Transaxial CT and corresponding fused PET-CT, (b) coronal CT and corresponding fused PET-CT sectional images showing non-FDG avid thrombus in right superior pulmonary vein extending upto the left atrium (arrow)

A peripherally enhancing hypodense lesion measuring 1.5 cm x 1.4 cm with minimal perilesional edema and no significant FDG uptake was seen in left frontal cortex [Figure 4].
