Reversible cerebral vasoconstriction syndrome associated with hormone therapy for intrauterine insemination.

INTRODUCTION: Reversible cerebral vasoconstriction syndrome (RCVS) comprises a heterogeneous group of acute neurological diseases which are characterized by thunderclap headache and evidence of reversible multifocal constriction of cerebral arteries. A number of precipitating factors have been described in the literature, including recent childbirth and use of vasoactive substances. CASE DESCRIPTION: Here we present the case of a female patient with RCVS which occurred in the setting of hormonal ovarian stimulation for intrauterine insemination. DISCUSSION: This case possibly contributes to the understanding of the pathophysiological mechanisms underlying reversible cerebral vasoconstriction.
