A rare case of recurrence of a metastatic brain tumor which disappeared due to chemotherapy only is reported. A 52-year-old male was noticed to have an abnormal shadow in his chest X-P at a routine medical examination, so a close examination was made. He was diagnosed as having right renal cell carcinoma which had metastasized to the lung. He was treated by intra-arterial infusion of anti-cancer drugs and embolization of the right renal artery. No renal symptom was seen, growth of the primary tumor stopped, and the abnormal shadow in his chest diminished. However, weakness in the left hand appeared 19 months after the first examination and he was admitted to our clinic. He was alert, but slight left hand weakness was observed. CT scan revealed a diffusely enhanced mass in the right parietal lobe. Total removal of the brain tumor was performed and the histology was metastasis of renal cell carcinoma. He was discharged and was able to walk but he had slight left hemiparesis. UFT 6 capsules a day were administrated in our out-patient clinic. However, CT scan revealed recurrence of the tumor 2 weeks after discharge, we followed up with conservative treatment, and no growth of the tumor was seen. It disappeared 5 months after discharge after being treated with UFT only. We regard UFT as having been effective in this case.
