“…The azygous vein originates below the diaphragm from the right ascending lumbar vein, ascends to the T5 level where it arches right and anteriorly over the right mainstem bronchus, and ultimately empties into the SVC [9]. Using 3-D reconstruction of the original CT images, we highlight the exaggerated trajectory of the azygous system with an enlarged hemiazygous that bypasses the hepatic inferior vena cava obstruction (Fig.…”
