We report a 67-year-old woman with APS who presented with ischemic stroke due to RCVS. She was treated with low-dose cilostazol and lomerizine hydrochloride, which resulted in functional improvement and recovery of vasoconstriction within 12 weeks. Her plasma endothelin-1 level was decreased after relief of vasoconstriction, compared with the pre-treatment condition. Increased plasma endothelin-1 may be related to the underlying pathomechanism of RCVS with APS, against which cilostazol and lomerizine hydrochloride could be effective.
