Singhal et al1 reported a cohort of 139 patients with reversible cerebral vasoconstriction syndrome (RCVS) and concluded that patients with RCVS have a unique set of clinical imaging features, with no significant differences between subgroups. This study again reveals a high incidence of hemorrhagic events in RCVS. However, we have some concern regarding the causes of hemorrhagic complications in RCVS.
