Reversible cerebral vasoconstriction syndrome (RCVS) is a clinicoradiological syndrome that occurs due to dysfunction of cerebrovascular autoregulation. It is characterized by recurrent thunderclap headache from cerebral vasoconstriction which can cause ischemic infarction, spontaneous intraparenchymal and subarachnoid hemorrhage. This syndrome can be triggered by a variety of etiologies including medications, infectious, and inflammatory conditions. The diagnosis is often delayed due to unawareness among the health-care providers and delayed neuroimaging evidence of vasoconstriction with or without ischemic and/or hemorrhagic infarction. Status migrainosus is a prevalent condition requiring emergency room visits and inpatient admission. Thus, patients with RCVS can be easily misdiagnosed with migraine. We report a patient with RCVS misdiagnosed as status migrainosus with visual aura, treated with intravenous dihydroergotamine with worsening of cerebral vasoconstriction and lead to ischemic and hemorrhagic complications. We discuss this complication and provide guidance on differentiating between migraine and RCVS.
