Abstract

A 68-year-old male developed a solitary metastasis in the choroid plexus of the right lateral ventricle 7 years after left nephrectomy for renal cell carcinoma. The lesion was totally removed and the patient has been free from recurrence for 30 months postoperatively. Pure solitary metastasis to the choroid plexus is very rare, but five of the 15 cases originated from renal cell carcinoma. There may be a link between this type of metastasis and the slowly progressive type of renal cell carcinoma.
