Influence of physiologic hormonal modification and of hormonal treatment in a patient with a history of migraine with aura.

We present the case of 48-year-old woman suffering from migraine with aura (MA) since menarche. During her life the patient frequently presented catamenial MA attacks with an increasing frequency during pregnancy in particular in the second and third trimesters, and then during breast-feeding. Treatment with oral contraceptive (OC) for endometriosis and later with cyclophosphamide, methotrexate, fluorouracil (CMF) for breast cancer produced a higher number of attacks. Instead, she referred an improvement with gonadotropin releasing hormone agonist (GnRH-a) for the treatment of endometriosis and then with tamoxifen as hormonal therapy after mastectomy and chemotherapy for breast cancer. We highlight the importance of physiological hormonal modification and hormonal therapies on the course of MA.
