과거의 가역뇌혈관수축증후군에 기인한 지속 두통 환자에서 프레마네주맙 치료로 유의한 호전을 보인 증례 = Persistent Headache Attributed to Past Reversible Cerebral Vasoconstriction Syndrome Demonstrating Significant Improvement with Fremanezumab

다국어 초록 (Multilingual Abstract)

A 45-year-old woman with a history of migraine experienced thunderclap headaches, after which cerebral vasospasm was confirmed by brain magnetic resonance angiography.
Nimodipine treatment initially improved the headache, but moderate daily headaches persisted despite vasospasm resolution. Conventional headache medications including topiramate, propranolol and amitriptyline proved ineffective. Treatment with fremanezumab, a calcitonin gene-related peptide (CGRP)-targeted therapy, resulted in significant reduction of headache frequency and intensity after 3 months. This case suggests the potential effectiveness of CGRP inhibition for persistent headaches following reversible cerebral vasoconstriction syndrome.
