Lymphomatous deposit. a, b Pre- and post-contrast sagittal T1-weighted MR images showing a solitary extra-axial lymphomatous deposit with a wide dural base and avid enhancement. It is lobulated, and its border is ‘fluffy’ and less distinct than that of the typical meningioma. There was no skull hyperostosis or intratumoural calcification on CT imaging. c Axial T2-weighted MR image of the same lesion showing marked vasogenic oedema. d Maximum intensity projected FDG PET image demonstrates avid tracer uptake within the lesion
