Abstract:
We report a case of solitary brain metastasis from renal cell carcinoma (RCC) 14 years after nephrectomy. A 46-year-old female had sudden onset of headaches, aphasia, gait disturbance and right hemiparesis. A brain CT revealed a cystic tumor in the left parietal area, which was surgically removed completely. Microscopic appearances of the brain tumor were similar to those of the primary RCC. Positive immunoreaction for epithelial membrane antigen (EMA) and keratin confirmed the diagnosis of metastatic RCC. This is the second case of solitary brain metastasis from RCC occurring more than 10 years after nephrectomy.
