Abstract:
Retroperitoneal paragangliomas arise from specialized neural crest cells symmetrically distributed along the aorta in association with the sympathetic chain. If this tissue aggregates in the adrenal medulla pheochromocytoma may arise. When it remains in the paraaortic sites it could develop into extra-adrenal, retroperitoneal paraganglioma. We report a case of extra-adrenal paraganglioma in the renal hilum intimately related to the left side of a double inferior vena cava. To the best of our knowledge such an association has never been described before. The clinical significance of this venous anomaly is reviewed.

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...
Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla
Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
The greater splanchnic nerve, formed by the...

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.
