Computed tomography of the chest with intravenous contrast (coronal view) demonstrating thrombus within the left subclavian, left brachiocephalic and right distal brachiocephalic veins with extension to the proximal superior vena cava (Red Arrow). A left-sided pleural effusion is present as well. (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)

Computerized topography of the chest with intravenous contrast demonstrated superior vena cava extrinsic compression by surrounding lymph nodes and a thrombus within the left subclavian, left brachiocephalic and right distal brachiocephalic veins with extension to the proximal superior vena cava (Fig. 1).
Venogram of the chest under fluoroscopy demonstrating decreased blood flow in bilateral brachiocephalic and SVC due to thrombus (Red Arrows). (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)
