Abstract
Reversible cerebral vasoconstriction syndrome is a clinical-radiological entity characterized by severe and hyperacute onset-thunderclap headache, with or without additional neurological signs and symptoms in relation to a segmental cerebral arterial vasoconstriction that resolves spontaneously at around 3 months. Its clinical manifestations are similar to other diseases, and additionally there are multiple associated etiological factors; early diagnosis becomes a challenge, but is essential to establish proper treatment and prevent complications. We present the case of a female patient in whom the repetitive performance of the Valsalva maneuver without another concomitant factor was documented as etiology, the interventions performed are presented and a narrative review of the topic is made with emphasis on differential diagnosis.
