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.

Veins of Thorax
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.

Overview of Systemic Veins
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the middle...
Veins of the Abdomen and Pelvis
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...
