Radiographical findings on positron emission tomography (PET) scan showed hyperactivity along the left lateral aspect of the tongue and a mildly hypermetabolic left level IIa cervical lymph node with no evidence of distant metastases (Figure 1).
Axial PET scans revealing a new left apical pleural mass (white arrow) (a) and cardiac metastasis (blue arrow) (b).

In early 2018, a PET scan (Figure 2) and magnetic resonance imaging (MRI) of the chest (Figure 3) showed a new 3.4 cm left apical pleural mass encasing the left subclavian artery and abutting the left subclavian vein, both of which were patent. A PET/CT scan demonstrated hypermetabolic lesions in the left neck, right thigh muscles, lung parenchyma, heart, anterior mediastinum, left scapula, and posterior right rib (Figure 2).

Further diagnostic imaging with a cardiac MRI was performed, which revealed a mass infiltrating the left ventricle, inferior myocardium, epicardial fat, and pericardium with associated mobile thrombus formation (Figure 4).
