A RARE CASE OF METASTASIS OF BREAST CARCINOMA TO INTRACRANIAL MENINGIOMA

Abstract

A 56-year-old woman complaining of a tender mass in the left breast and a headache entered our hospital. Pathologic examination of a core-needle biopsy yielded a definitive diagnosis of breast carcinoma. Chest-computed tomography scan and bone scintigraphy revealed axillary lymph node metastasis and bone metastasis. Brain magnetic resonance imaging revealed a solid well-circumscribed tumor in the right frontal-temporal lobes. The patient underwent successful tumor resection. Pathologic examination revealed breast carcinoma in the tissue of a fibrous meningioma. Hormonal therapy was subsequently given. Tumor-to-tumor metastasis is a rare event. We report an uncommon case of metastasis of breast carcinoma to an intracranial meningioma. A review of the literature and discussion of this uncommon event are presented.
