A case of anomalous (subaortic) position of the left brachiocephalic vein was incidentally detected on computed tomography images. Magnetic resonance angiography was performed to demonstrate the relationship of this vessel with other vascular structures. The anomalous vein was formed by the union of the left internal jugular and left subclavian veins. This vein passed downward along the left lateral side of the aortic arch, entered the aorticopulmonary window, descended in the mediastinum between the ascending aorta and the trachea and joined with the right brachiocephalic vein to form the superior vena cava. No cardiac anomalies accompanied the subaortic left brachiocephalic vein in the present case. We present the computed tomography and magnetic resonance angiography findings of this rare anomalous vein.
在计算机断层扫描图像上偶然发现一例左头臂静脉异常（主动脉下）位置的病例。进行了磁共振血管造影以显示该血管与其他血管结构的关系。异常静脉由左颈内静脉和左锁骨下静脉汇合而成。该静脉沿主动脉弓左侧向下走行，进入主动脉肺动脉窗，在升主动脉和气管之间的纵隔内下行，并与右头臂静脉汇合形成上腔静脉。本例中，主动脉下左头臂静脉未伴有心脏异常。我们展示了这条罕见异常静脉的计算机断层扫描和磁共振血管造影结果。
