Reversible cerebral vasoconstriction syndrome (MRI)

In this brain MRI (fluid attenuated inversion recovery or FLAIR image) from a patient with RCVS, there is a small cortical surface subarachnoid hemorrhage overlying the left hemisphere (black arrow) and multiple dot- and linear-hyperintensities in the sulcal spaces of the right hemisphere (white arrows), indicating slow blood flow within dilated cortical surface arteries.
