Introduction: Thunderclap headache (TCH), defined as a severe headache with acute-onset, is a well-known presentation of subarachnoid hemorrhage (SAH) and other intracranial pathologies involving the CNS.1 However, reversible cerebral vasoconstrictive syndrome (RCVS), defined by recurrent headaches (often TCHs) with or without focal deficits, and segmental vasoconstriction of the cerebral arteries, is a remarkably common yet under-recognized cause of TCH.1 While RCVS generally follows a benign course, RCVS may precipitate catastrophic complications including SAH and ischemic or hemorrhagic stroke in a minority of patients.2 This case aims to enhance the recognition of this relatively common, and potentially life-threatening, cause of TCH. …show more content…

The patient was initially evaluated at two outside hospitals with non-contrast head CT and CSF analysis which remained grossly unremarkable. Following both evaluations, the patient was discharged with oral analgesics. Following the third episode, the patient presented to our emergency department where was admitted to the Hospital Neurology Service. Upon admission, vital signs and laboratory studies were grossly unremarkable. MR angiography of the head revealed multiple foci of segmental vasoconstriction of the anterior and posterior circulation suggestive of RCVS. The patient was treated with oral calcium channel blockers and discharged home with a mild persistent
