Primary carcinoma of the choroid plexus with metastatic dissemination within the central nervous system

The authors present a case of primary carcinoma of the choroid plexus in a 26-years-old female, localized in the left lateral ventricle. Four years after total removal plus local radiotherapy, the patient presented with an intraparenchymatous metastasis in the right cerebellar hemisphere and intraspinal metastatic seeding. With this kind of malignant growth, a therapeutic approach consisting of radical removal of the tumour plus radiotherapy to the whole neuraxis is proposed.
