title: [A rare case of intracranial meningioma with intratumoral metastatic breast cancers].
abstract: We report an uncommon case of breast cancer metastasis to an intracranial meningioma. A 47-year-old female was admitted to our hospital due to general convulsion. She had undergone a radical operation for left breast cancer 4 years refore, and received postoperative adjuvant therapies. MRI revealed a solid well-circumscribed tumor in the right frontal convexity. The patient underwent tumor resection successfully. The pathological examination revealed ductal carcinoma in the tissue of a transitional meningioma. Tumor-to tumor metastasis is a rare event. Literature review and discussion of such an uncommon occurrence was presented.
