Reversible cerebral vasoconstriction syndrome (RCVS): a transient condition being underdiagnosed?

Description A 68-year-old woman was admitted with a 6-day history of sudden onset, throbbing headache associated with transient visual disturbance. The current case has been presented to emphasise that it is important to consider angiograms in more patients presenting with sudden onset headaches, even when SAH has been excluded, as they can potentially be treated appropriately, possibly preventing complications.
