 Metastatic brain tumor occasionally results in multiple cerebral hemorrhages. Here, we report a case of metastatic brain tumor complicated by multiple repeated cerebral hemorrhages. An 80-year-old man with a history of removal of lung cancer was admitted to our hospital because of disturbed consciousness following headache. A brain CT revealed a mass lesion of 40-mm diameter in the left cerebellum and a mass lesion of 2-mm diameter in the right temporal lobe. The cerebellar mass lesion showed homogeneous iso-density, indicating a subacute phase hemorrhage. Two days later, a follow-up CT revealed that the mass lesion had become high-density, indicating complication by a fresh hemorrhage. Hematoma was removed and histological examination was performed on the cerebellar lesion. There was leakage of dark-red liquid intraoperatively, and histological examination revealed an adenocarcinoma, indicating metastasis of the lung cancer. Additionally, necrosis and hemorrhage were identified. Postoperatively, whole brain irradiation was performed. The right temporal lesion gradually enlarged but disappeared after irradiation. In conclusion, multiple brain metastases may result in multiple cerebral hemorrhages. Repeated hemorrhage from necrosis of the carcinoma causes a slowly growing hematoma.
