Objective:
With the improved prognosis of patients with hepatocellular carcinoma, the likelihood of diagnosing adrenal metastasis has increased. We performed percutaneous ethanol injection for adrenal metastasis in seven patients and evaluated its efficacy.
Conclusion:
Percutaneous ethanol injection was successfully performed in nine nodules in seven patients. During follow-up, six nodules in five patients showed no increase in size. Four patients were alive 6-28 months after injection, one patient died of hepatic failure, one of brain metastasis, and one of multiple metastases. Percutaneous ethanol injection can be an alternative treatment for adrenal metastasis of hepatocellular carcinoma.
