Characterization of mass. a Axial FDG-PET/CT scan in a patient with known thyroid cancer showed intensely hypermetabolic lesion (arrow) in the heart, which could not be localized clearly. b Four-chamber delayed enhancement cardiac MRI shows the mass to be entirely located within the left ventricular cavity. The mass has two distinct components, an enhancing component (red arrow) and a non-enhancing component (yellow arrow), which correspond to metastatic lesion and superimposed and bland thrombus, respectively. The patient was placed on anticoagulants in addition to chemotherapy
