Multiple oncotic intracranial aneurysms and cardiac metastasis from choriocarcinoma: case report and review of the literature.

Ten cases of oncotic intracranial aneurysms from choriocarcinoma have been reported previously. We report an eleventh case with four aneurysms secondary to metastatic choriocarcinoma. These aneurysms seemed to arise from cephalic embolization of neoplastic tissue from an implant of choriocarcinoma in the left ventricle of the heart.
