Multiple neoplastic intracerebral aneurysms associated with renal cell carcinoma

Abstract

Intracranial neoplastic cerebral aneurysms (NCA) from metastasis are a is an extremely rare disease entities. NCA has been reported in a very small number of patients. Most cases of NCAs are usually complicated with cardiac myxomas and choriocarcinoma, other tumors are lymphoma, cardiac myxosarcoma, and rarely lung carcinoma. And these are much less common than myxomas and choriocarcinoma. Although lung cancer is very common neoplasm and have high metastatic potential to brain, there have only been 6 published reports of intracranial cerebral aneurysms secondary to metastatic lung cancer. But, we could not find any previous reports about NCA associated with renal cell carcinoma. We present multiple intracerebral aneurysms associated with renal cell carcinoma, causing subarachnoid hemorrhage (SAH) and intracerebral hemorrhage (ICH).
