Singular case of third ventricle metastasis of colorectal carcinoma--case report.

Third ventricle tumors are uncommon central nervous system lesions and unusual locations for metastatic colorectal cancer. We present a case of a 68 year old woman with a solitary 3rd ventricle lesion found on a computed tomography scan of the brain and the synchronous mass of the right colon. The aim in this case was local control of cerebral lesion with pathological diagnosis. Surgery was followed by a short-term good evolution but with sudden death.
