AbstractObjective We investigated the clinical characteristics of patients with reversible cerebral vasoconstrictor syndrome who had a history of migraine before the onset and considered the relationship between these two pathologies. Methods We investigated 98 patients who underwent magnetic resonance angiography within 14 days of the onset of reversible cerebral vasoconstriction syndrome at our hospital. Of these, 11 cases involved recurrences, so data from 87 patients were analyzed. Materials All consecutive patients diagnosed with reversible cerebral vasoconstrictor syndrome at our institution between October 2010 and July 2021. Results Fifty of the 87 patients (57%) had a history of migraine. A multivariate analysis revealed that the following clinical factors were significantly more frequent in patients with a history of migraine than in those without such a history: female sex; emotional situations as a trigger of the onset; presence of deep and subcortical white matter hyperintensity, absence of vasoconstriction in the M1 portion of the middle cerebral artery, and absence of other cerebral lesions on initial magnetic resonance imaging; absence of vasoconstriction of the basilar artery on follow-up magnetic resonance imaging; and progression of deep and subcortical white matter hyperintensity in the chronic stage. Conclusion Reversible cerebral vasoconstrictor syndrome patients with a history of migraine showed clinical features of migraine, including one aspect of cerebral small-vessel disease due to endothelial dysfunction, as a common causative condition.
