The patient underwent a whole-body positron emission tomography - computed tomography (PET-CT) that showed significant activity in the right tonsillar mass with a maximum dimension of 4.8 cm and standard uptake value (SUV) of 16.5 along with prominent right level 2 lymph nodes measuring 1.1 cm with SUV activity of 3.3 (Figure 1).

A follow-up PET scan 8 weeks later demonstrated significant improvement in large right palatine tonsil mass with small region of mild residual hypermetabolic uptake (Figure 2).

However, he was noted to have new FDG-avid 4.9 cm cardiac mass in the anterior wall of right ventricle (Figure 3).

Cardiac MRI obtained confirmed a 4.6 cm right ventricular mass (Figure 4); thus, the patient was referred to thoracic surgery for the removal of the cardiac mass.
