title: Resection of a malignant paraganglioma located behind the retrohepatic segment of the inferior vena cava.
abstract: BACKGROUND
  Resection of a retrocaval paraganglioma is technically challenging due to limited tumor accessibility and proximity to the vena cava.
  
  
  METHODS
  A large, malignant paraganglioma was found behind the retrohepatic segment of the inferior vena cava of a 60-year-old male. During resection of this rare paraganglioma, the left lateral lobe of the liver, a portion of the caudate lobe of the liver, and the gallbladder were also removed. Unfortunately, the patient died six months after surgery due to hepatic metastasis.
  
  
  CONCLUSIONS
  This case demonstrates that a partial hepatectomy may be necessary to improve tumor accessibility during resection of a retrocaval paraganglioma, particularly if the tumor is proximal to the vena cava. Furthermore, palliative treatments may help prevent tumor recurrence and metastasis of malignant paragangliomas.
