BACKGROUND Pheochromocytomas with inferior vena cava(IVC)or renal vein tumor thrombus are rare.Surgical management is the first choice.CASE SUMMARY We presented a 42-year-old man with adrenal pheochromocytoma and delayed tumor thrombus detection in the renal vein at the entrance of the IVC three months after adrenalectomy.We performed laparoscopic adrenalectomy during the first surgery and robot-assisted laparoscopic nephrectomy and resection of tumor thrombus during the second surgery.CONCLUSION We report the surgical management of a patient with adrenal pheochromocytoma with tumor thrombus at the entrance of the IVC.Robot-assisted laparoscopic surgery is safe and efficient.
