Abstract:
The prevalence of intravascular extension of bone sarcomas of the pelvis is unknown. We report a case of intravascular extension of an osteogenic sarcoma of the pelvis into the vena cava, correlating the pre-operative imaging findings with the intra-operative findings and specimen analysis. A brief review of the literature is provided.

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...

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.
