Intracranial hemorrhage due to brain metastasis from hepatocellular carcinoma--case report.

The authors report a case of repeated brain metastases from hepatocellular carcinoma (HCC) in a 70-year-old male, who had underwent liver segmentectomy for HCC 5 years earlier. He developed intracerebral hemorrhage in the right parietal region, which was considered to be intratumoral because the metastatic tumor was detected in the same region. Total removal of the tumor and hepatic artery embolization followed by ethanol injection for recurrent HCC were performed. One month later, a metastatic tumor was discovered in the upper vermis and was totally removed. Both metastatic brain tumors were histologically verified as Edmondson grade 2 HCC. Four months later, multiple metastases to the left frontal region and the upper vermis occurred, and he died of pneumonia. Brain metastasis from HCC is rare; nine such cases have been reported in the literature, of which eight cases developed intracranial hemorrhage as in the present case.
