case_images: Computed tomography (CT) of his thorax, abdomen, and pelvis revealed a smooth oval right anterior mediastinal mass measuring 3.6 cm x 1.6 cm x 2.6 cm (transverse [TS] x length [LS] x cranial-caudal [CC]), and bilateral diffusely thickened adrenals (Fig. 1A and 1B).

case_images: Positron emission tomography (PET)/CT with fluorine-18-fluorodeoxyglucose (18FDG) and gallium-68-DOTATATE (68Ga-DOTATATE) demonstrated a mildly dual-tracer avid mediastinal mass, which had no invasion into the right atrium (Fig. 2A and 2B).
