Özet

Obstruction of the blood flow from the superior vena cava (SVC) to the right atrium causes the SVC syndrome. The azygos system is the most important way to overcome SVC obstruction. Azygos vein enlargement can be seen secondary to the SVC syndrome. Although a few cases showing F-18-FDG uptake along the SVC in SVC syndrome were reported before, F-18-FDG PET/CT findings of azygos vein enlargement have not been documented yet. Herein, we presented an intriguing case of azygos vein enlargement secondary to SVC syndrome on F-18-FDG PET/CT.
