A Case of Migraine Aura Status in a Migraine Patient With Typical Aura Without Headache.

Migraine aura status (MAS) is a rare complication of migraine and is listed in the appendix of the International Classification of Headache, Third Edition. MAS occurs in migraine with aura (MwA) patients, with at least three auras occurring over a period of three days. We describe a case of MAS associated with a patient who had a migraine with a typical aura without headache (TAWH). She has experienced only visual auras, including periods of MAS complications, and has not experienced headaches or other auras, including sensory, speech, and motor. The patient is a 45-year-old woman. She had discomfort with visual aura without a headache every two to three months. The visual aura began to gradually darken a portion of the right side of the visual field binocularly, which gradually expanded around it and was surrounded by iridescent flashes running in a zig-zag pattern to the periphery. The area of the visual field abnormality gradually decreased and disappeared after approximately 15 minutes. One day, she had an aura once after dinner, and when she awoke without any trigger after going to bed, the aura appeared and repeated approximately three times. She experienced three to four auras the next day and the day after. In the six-month follow-up period, there was no further recurrence of MAS. Most previous reports of MAS have been associated with typical MwA, and there have been few other reports of MAS associated with TAWH as far as we could investigate.
