Typical meningioma. a Axial T2-weighted MR image of a well-circumscribed meningioma indenting the cortex with a small cleft of CSF. b Coronal post-contrast T1-weighted image showing uniform enhancement, an enhancing-thickened dural tail and hyperostosis of the overlying calvarium. c Unenhanced CT illustrating the adjacent hyperostosis of the skull. d Magnetic resonance spectroscopy of a similar meningioma demonstrating a high choline:creatine (Cho:Cr) ratio and a low N-acetylaspartate (NAA) peak
