Fig 1 (A–C) Triggered computed tomographic pulmonary angiography through a contrast injection into the left arm. Starting at (A) the thoracic inlet, the axial slices demonstrate the enhanced left brachiocephalic collar configuration with (B) branching and (C) subsequent reforming above the azygous orifice of the superior vena cava (SVC). (A = aorta; Aa = ascending aorta; B = brachiocephalic vein; B1 = supraaortic branch; B2 = subaortic branch; C = azygous orifice, Da = descending aorta.)

Fig 2 Three-dimensional reconstruction with vascular segmentation of the central vasculature demonstrating the anomalous relationship of the vein and the aortic arch and pulmonary artery (PA). (A) Anterior view and (B) posterior view. (A = aorta; Aa = ascending aorta; B = brachiocephalic vein; B1 = supraaortic branch; B2 = subaortic branch; Da = descending aorta; PA = pulmonary artery; SVC = superior vena cava.)
