Breast cancer metastasis. a Post-contrast axial CT showing a strongly enhancing extra-axial lesion with a wide dural base and associated vasogenic oedema. There is no bony hyperostosis or erosion. b T2-weighted axial image of the same lesion which has an indistinct cortical interface suggestive of involvement. c Post-contrast axial T1-weighted MR image of the lesion with some slight heterogeneous but strong enhancement. d Diffusion-weighted imaging demonstrated intermediate restricted diffusion within the lesion
