Surgical management of a neuroendocrine tumor of the inferior vena cava

Neuroendocrine tumors occurring outside of the gastrointestinal tract or lungs are very few, and to find a primary neuroendocrine tumor of the infrahepatic inferior vena cava (IVC) is extremely rare. We present a case of a patient with a large, 7 × 4 cm neuroendocrine tumor of the IVC, where the IVC and renal veins were completely extirpated and not reconstructed. As a result, the liver was anastomosed to the intrapericardial IVC, and the patient relied on collateral drainage. After an initial postoperative period of anasarca and weight gain, she ultimately recovered fully with no evidence of recurrence in the IVC.
