[A case of multiple metastatic brain tumors with repeated intracerebral hemorrhages]

We report a case of multiple metastatic brain tumors with repeated intracerebral hemorrhages. A 73-year-old man suffered from a cerebellar hemorrhage. Subsequent hemorrhages repeatedly occurred in the right temporal lobe, the 4th ventricle, the midbrain, and the septum pellucidum. Three months after admission, CT revealed enhanced masses with surrounding edema in the cerebellar vermis and midbrain, suggesting brain tumors. We eventually diagnosed these masses in an autopsy as metastatic brain tumors of lung adenocarcinoma. Intravascular embolization with tumor cells was a probable cause of the multiple repeated intracerebral hemorrhages.
