We report a case of hydrocephalus due to brain metastasis from renal cell carcinoma treated with axitinib. A 65-year-old man had undergone right radical nephrectomy for renal cell carcinoma in 2010. The pathological diagnosis indicated clear cell carcinoma G3, pT1a. After adjuvant treatment with interferon-α, computed tomography, in 2011, revealed multiple lung metastases. He was administered sorafenib. Because of progressive lung metastases, sunitinib was administered. The lung metastases were progressive and bone scan revealed multiple bone metastases. The patient was administered axitinib 10 mg/day in February 2014. Brain metastases were found in both the lateral ventricles in the same month and were controlled using axitinib. The patient, however, experienced adverse events such as diarrhea and hand foot syndrome, and the axitinib dosage was titrated. Cognitive function declined rapidly in August 2015. Brain magnetic resonance imaging revealed hydrocephalus due to brain metastasis from renal cell carcinoma. Axitinib was administered again. Cognitive function improved within approximately 10 days. Furthermore, hydrocephalus improved, and the patient was discharged on the 21st day.
