Bilateral subdural hematomas from spontaneous intracranial hypotension

FLAIR image on brain MRI (A) shows bilateral hyperintense subdural hematomas (arrows) that compress underlying cerebral cortex. Axial post-contrast T1-weighted image (B) shows uniform enhancement of the dura (arrowheads). Sagittal post-contrast T1-weighted image (C) shows diffuse dural enhancement (dashed arrows), pituitary hyperemia (circle), and brain sagging, suggestive of intracranial hypotension.
