Abstract

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.

Keywords: Pheochromocytoma; Tumor thrombus; Robot-assisted laparoscopic surgery; Case report; Renal; Magnetic resonance imaging

Core tip: We report a rare case of adrenal pheochromocytoma on the left side with delayed detection of tumor thrombus at the entrance of the inferior vena cava and share our experience in surgical management. A similar case has not been reported previously. Nephrectomy is required when the tumor is on the left side and robot-assisted laparoscopic surgery is safe and efficient.
