BACKGROUND
Resection of a retrocaval paraganglioma is technically challenging due to limited tumor accessibility and proximity to the vena cava.
CASE PRESENTATION
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.
CONCLUSION
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.
背景
由于肿瘤可及性有限且靠近腔静脉，腔静脉后副神经节瘤的切除在技术上具有挑战性。
病例报告
在一名60岁男性的肝后段下腔静脉后方发现一个巨大的恶性副神经节瘤。在切除这个罕见的副神经节瘤过程中，还切除了肝脏左外叶、部分肝尾状叶和胆囊。不幸的是，患者术后六个月因肝转移死亡。
结论
该病例表明，在切除腔静脉后副神经节瘤时，特别是当肿瘤靠近腔静脉时，可能需要进行部分肝切除术以改善肿瘤可及性。此外，姑息治疗可能有助于预防恶性副神经节瘤的肿瘤复发和转移。
