To the Editor We read with interest a recent Images in Neurology article, which presented an example of reversible cerebral vasoconstriction syndrome (RCVS).1 Sorensen1 described a woman who presented with tonic-clonic seizure following synthetic cannabis use, with improvement after 24 hours. The only presented images are T2-weighted sequences that demonstrate bilateral hyperintensities involving cortical and subcortical regions.
