case_images: Sagittal T1-weighted MRI scan of the head showing 5.2 mm smooth dural thickening and enhancement anteriorly (dotted label) consistent with IHP, as opposed to GPA which typically displays local bone destruction at the base of the skull and vascular inflammation.. MRI: Magnetic resonance imaging; IHP: Idiopathic hypertrophic pachymeningitis; GPA: Granulomatosis with polyangiitis

case_images: Repeat MRI demonstrated ~5 millimeter smooth dural enhancement and thickening consistent with pachymeningitis (Figures 1, 2), and lumbar puncture findings included elevated oligoclonal bands and an elevated IgG index.
case_images: Coronal T1-weighted MRI scan showing 4.9 mm smooth dural thickening and enhancement (dotted label) consistent with IHP, as opposed to GPA which typically displays local bone destruction at the base of the skull and vascular inflammation..
