title: Metastasis of breast carcinoma to intracranial meningioma.
abstract: A patient who had been treated for bilateral breast carcinoma subsequently developed a metastatic breast lesion in a meningioma. Although it is not uncommon for more than one tumor to occur in the same patient, metastases from one tumor into another tumor are rare (''tumor to tumor'' phenomenon). Meningiomas are the most common primary, intracranial tumors to harbor metastases, the majority of which arise from breast and lung carcinomas. Patients with a history of breast cancer and a solitary, intracranial mass with radiological features consistent of meningioma should be evaluated surgically. The lesion may be a primary cerebral malignancy, a metastatic lesion, or a meningioma with or without a metastatic lesion.
