IgG4-related hypertrophic pachymeningitis with skull invasion. a Post-contrast coronal T1-weighted MR image showing linear dural thickening and enhancement overlying the left cerebral convexity. Note that the overlying calvarial bone marrow signal is abnormal. b Apparent diffusion coefficient (ADC) map showing restricted diffusion in the lesion overlying the left parietal region. c Post-contrast axial T1-weighted image of the same lesion with enhancing soft tissue seen invading the skull. d Axial fluid attenuated inversion recovery (FLAIR) image showing the lesion is predominantly hypointense due to fibrosis with foci of hyperintensity
