摘　　要：Background: Skull vault lesions are rare and represent 1% - 2% of all bone masses. Most cerebral metastases are the intra axial tumors, whereas extra-axial masses mimicking meningioma are extremely rare. Case presentation: A 35-year-old woman with a history of mastectomy left breast cancer 5 years below radiotherapy was referred to the neurosurgery department with a parietal extra-axial mass parietal evolving for one year. CT scan with Magnetic resonance imaging revealed an extra-axial tumor with lysis bone. A craniotomy was performed to remove the mass that was located extra-axial. Histopathological examination revealed metastasis. Conclusions: Lesion skull vaults are rare but they should be considered in the differential diagnosis of intraosseous meningioma lesions. In this report, we discuss the clinical aspects of cases we observed, in which the metastasis bone was found thanks to the histological examination of a calvarial mass after surgery.Background: Skull vault lesions are rare and represent 1% - 2% of all bone masses.
