Fig. 1 42-year-old man with aortic body paraganglioma (patient 1).
Contrast-enhanced axial CT image shows enhancing mass (arrows)
projecting in anterior direction from aortopulmonary groove. Note central low
attenuation suggesting central necrosis.
Fig. 2A 49-year-old man with aortic body paraganglioma (patient 4). Coronal
MR image shows intermediate T1 signal intensity mass (arrow) embedded
in aortopulmonary groove.
Fig. 2B 49-year-old man with aortic body paraganglioma (patient 4). Axial MR
image shows high T2 signal intensity mass (arrows) embedded in
anterior aortopulmonary groove.
Fig. 4 39-year-old man with aortic body paraganglioma (patient 2).
Contrast-enhanced axial CT shows large heterogeneously attenuating
infiltrative mass (arrows) within posterior aortopulmonary groove
with areas of poor enhancement, suggesting necrosis.
Fig. 5 Unidentified patient with supraaortic paraganglioma (patient 5).
Contrast-enhanced axial CT image shows enhancing soft-tissue density mass
arising from less common location, between right subclavian and common carotid
arteries. Note aggressive local behavior with chest wall invasion (white
arrows) and destruction of manubrium (black arrow).
