title: Breast carcinoma metastasis and meningioma. A case report.
abstract: BACKGROUND
  The simultaneous occurrence of meningioma and breast cancer with or without brain metastasis is an unusual but well-known event. However, contiguous occurrence of meningioma and brain cancer metastasis is a less rare evidence and we are aware of only one previously published case in the literature.
  
  
  METHODS
  A 72-year-old woman presented with headache, nausea and vomiting, and diminished mentation and memory. Seven years ago, she had had simple mastectomy at another hospital. Histopathologic examination had been reported as breast carcinoma. The patient had not gone to the controls and was unaware of the diagnosis. Cranial MRI examination of the patient showed two extraaxial masses. Histopathologic examination of the lesion at the frontal convexity, which was reported as en plaque meningioma radiologically, revealed meningioma but the other tumor at the sylvian fossa resembling the other meningioma was reported as breast carcinoma metastasis at histopathologic examination.
  
  
  CONCLUSIONS
  Although meningiomas have well-known radiological features, the other pathologies like breast metastasis may simulate them. A possible hormonal relationship between breast cancer and meningioma has not been clarified. We are not sure that this has played a role in dissociation of both tumor cells in our case.
