Intraventricular location of metastatic breast carcinoma: a case report.

Intraventricular neoplasms are uncommon central nervous system lesions that account for only 10% of all neoplasms and are unusual location of metastatic breast cancer. A 73-year-old woman with a medical history of breast carcinoma without any signs of metastatic lesions in the liver, lungs or bones and with an intraventricular tumorous lesion found on multislice computed tomography of the brain is presented. Surgery was indicated in order to confirm the diagnosis histologically and to gain local control of the metastasis. The patient was operated on using the neuronavigation guided transcortical approach. The tumor was removed using the Cavitron ultrasonic aspirator. Histopathologic examination revealed a metastatic breast carcinoma. Postoperative irradiation of the whole brain was performed.
