Her EEG was normal and her brain MRI (Figure 1) showed mild frontotemporal atrophy. A retrospective review of the brain MRI scans (Figures 1A,B) revealed diffuse pachymeningeal gadolinium enhancement and sagging of the brainstem, which were consistent with intracranial hypotension.
Post-treatment sagittal (A) and axial (B) T2-weighted MRI images show almost complete resolution of the findings of intracranial hypotension.

A repeat brain MRI scan was performed at the end of the fourth month (Figures 2A,B), which showed reduced brain swelling, less venous sinus congestion, and resolution of the tonsillar herniation.
