(a and b) Pre-operative sagittal and axial T1-weighted MRI with gadolinium contrast injection showing the homogenous enhancement by an olfactory groove meningioma. (c) Immediate post-operative brain CT shows tumor removal and vasogenic brain edema. (d) Post-operative sagittal T1-weighted MRI with gadolinium contrast reveals near total resection of the tumor
