title: [Hemichorea and oral contraceptives].
abstract: A 26 year-old woman presented with a left hemichorea while taking oral contraceptives (a combination of ethinyl-estradiol and norethisterone). There was marked improvement of the choreic movements after discontinuation of the oral contraceptive and complete resolution by 6 weeks. Induction of chorea is a rare complication of oral contraceptives. The possible mechanisms are briefly reviewed.
