The association of a metastatic carcinoma with a cerebral vascular malformation is presented. Although metastases into slow growing, vascular intracranial tumors are occasionally reported, this association does not seem to be reported previously. This case supports the hypothesis that distribution of intracranial metastases is closely related to the extent of intracranial blood flow. Hence, lesions with increased vascularity and flow such as vascular malformations are more likely to receive and entrap the metastatic emboli
