The ventricle is a rare site of brain metastases. Renal cell carcinoma has a higher propensity to metastasize to the ventricle compared with more common metastatic tumors (eg, lung cancer). The trigone is the predominant location for intraventricular metastases, presumably because of the high concentration of choroid plexus in this region. Surgical resection is an important component of the management of these lesions, particularly if there is only a single intraventricular lesion. Despite the deep location of these tumors within the ventricle, survival in patients undergoing surgery for them is comparable to that in patients receiving surgery for intraparenchymal metastases.
