Abstract
A rare case of right brachiocephalic vein (RBV) following an extramediastinal and
intrapulmonary course in the anterior portion of the azygos fissure is presented.
The appearance of the RBV and superior vena cava (SVC) on the chest radiograph in
patients with an azygos lobe reflects the variable relationship between these veins
and their mediastinal attachments. Computed tomography (CT) can easily demonstrate
the mediastinal vascular anatomy thereby allowing identification of such variants
and differentiation from anomalous pulmonary veins draining into the systemic vein.
