Abstract:
We present a case of a large saccular aneurysm arising from the azygos arch in an asymptomatic 62-year-old man. Chest radiography showed a well-defined right paratracheal mass. Dynamic computed tomography revealed marked enhancement of the mass suggesting a vascular structure, but no flow void was demonstrated on magnetic resonance imaging, probably due to slow turbulent flow.
