乳癌からの腫瘍組織内転移を伴った頭蓋内髄膜腫の1例

A Rare Case of Intracranial Meningioma with Intratumoral Metastatic Breast Cancers

Ⅰ．はじめに

　今回われわれは，乳癌からの腫瘍組織内転移を来した稀な頭蓋内髄膜腫の1例を経験した．その臨床像や病態を中心に，文献的考察を加え報告する．

　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.
