Patient 1. Axial non-contrast-enhanced CT brain scan revealing a left frontal convexity region hyperdense extra-axial lesion resembling an acute subdural hematoma (a, white arrow). A non-contrast-enhanced MRI scan exhibiting a T1-weighted isointense (b, white arrowhead) and T2/FLAIR-weighted hypointense left hemispheric pachymeningeal lesion with areas of hyperintense signal changes representing inflammatory foci (c, T2W, grey arrowhead; d, FLAIR sequence). The lesion did not show evidence of restricted diffusion (e). Three months after initiating prednisolone, there was complete resolution of the pachymeningeal lesion (f, FLAIR sequence)
