B: The tumor is hyperintense on T₂-weighted images. C: The tumor is hyperintense on sagittal FLAIR images. Arrow indicates the pre-central sulcus. D–F: MR images after the second surgery showing that the tumor has been subtotally removed. D: Axial T₁-weighted image. E: Axial T₂-weighted image. F: Sagittal FLAIR image. FLAIR: fluid attenuated inversion recovery, MR: magnetic resonance.
