Reversible cerebral vasoconstriction syndrome is an under-diagnosed disease that every radiologist should know about. This report demonstrates two female patients who presented with severe headache with subsequent angiographic findings of ‘bead and string’ appearances of the cerebral arteries at Circle of Willis, which resolved spontaneously within 3 months. Diagnosis of reversible cerebral vasoconstriction syndrome was made. The clinical and imaging characteristics in different modalities are discussed.

可逆性腦血管收縮綜合徵是一個常常未被明確診斷的疾病，對此放射科醫生都應有所了解。本文報 告兩名有劇烈頭痛的女性病人，血管造影顯示其威利斯（Willis）環腦動脈出現串珠狀表現，但於三 個月內自行緩解，後被確診為可逆性腦血管收縮綜合徵。本文討論此病的臨床及影像學特徵。
