Abstract
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.
Résumé
Un cas de position anormale sous-aortique de la veine brachiocéphalique gauche a été détecté accidentellement au cours d'un scanner. L'angiographie par résonance magnétique a été réalisée pour montrer les rapports de ce vaisseaux avec les autres structures vasculaires. La veine anormale était formée par l'union des veines jugulaire interne et subclavière gauches. La veine se dirigeait vers le bas le long du côté gauche de l'arc de l'aorte, traversait la fenêtre aorto-pulmonaire, descendait dans le médiastin entre l'aorte ascendante et la trachée et rejoignait la veine brachio-céphalique droite pour former la veine cave supérieure. Aucune autre anomalie cardiaque n'accompagnait la veine brachiocéphalique gauche sous-aortique dans le cas présenté. Nous présentons les données tomodensitométriques et d'angiographie par résonance magnétique concernant cette rare veine anormale.
