Right ventricular myxoma. a MIP of 18F-FDG PET/CT revealed a lesion with increased 18F-FDG uptake in the heart region (black arrow). b–d The transverse and e–g coronal view of selected PET, CT, and fused PET/CT images revealed a big mass with increased 18F-FDG uptake (white arrow, SUVmax 4.1), which located in the right ventricle. c and f On the non-contrast CT, the tumor presented homogeneous hypodensity, which was lower than the blood pool. h and i The transverse view of arterial and venous phases of CECT images revealed a huge filling defect in the right ventricle with mild enhancement in the venous phase (white arrowhead). j The histopathology revealed myxoma (H&E, magnification, × 400)
