title: Convexity meningioma and glioblastoma in collision.
abstract: An unusual case of benign convexity meningioma and glioblastoma in collision is presented. The preoperative diagnosis of this association is difficult to make based on symptomatology or computed tomography scans alone. This case supports the possibility of a malignant transformation within the gliosis surrounding a convexity meningioma.
