T2-weighted magnetic resonance imaging demonstrates homogeneous increased T2 signal intensity of the mass (white arrow). D, Four-chamber postcontrast T1 fat-saturated image demonstrates significant homogeneous enhancement of the mass (white arrow). E, Positron emission tomography image showing significant diffuse homogeneous 18F-fluoro-2-deoxy-D-glucose uptake throughout the mass. F, 10× hematoxylin–eosin stain of the tumor; tumor cells are in a nested growth pattern and separated by pink sclerotic collagenous stroma with well-vascularized lesion. G, 10× chromogranin immunohistochemical stain. H, 10× synaptophysin immunohistochemical stain.
