We report a case of choroid plexus metastasis from renal cell carcinoma causing intracerebral hemorrhage. A 70-year-old woman was admitted to our hospital because of intracerebral hemorrhage. She presented with severe headache and disturbed consciousness. She had left nephrectomy for renal cell carcinoma 15 years prior to admission. MRI revealed a well enhanced tumor with a peri-tumoral hemorrhage located in the trigone of the left lateral ventricle. The tumor and hematoma were totally removed via the left transcortical approach. The tumor was histologically diagnosed as clear cell carcinoma. She returned to her daily life with right homonymous hemianopsia and dyscalculia. A literature review suggested that a slowly progressive type of renal cell carcinoma is likely to metastasize to the choroid plexus of the lateral ventricle.
