Objectives:

To present a case of chorea gravidarum and conduct a review of the published literature on the treatment for this condition, and on maternal and fetal prognosis.

Materials and methods:

Case presentation of a 16-year-old primiparous patient admitted to a Level III public hospital at 8 weeks of gestation complaining of involuntary head and limb movements and right lower limb hyperreflexia lasting three days. The patient had a history of Sydenham chorea. Treatment with antipsychotics and benzodiazepines was given to manage symptoms, and with benzathine penicillin to address the etiology, achieving control at 14 weeks. Treatment was discontinued at 35 weeks and the patient went on to have normal delivery at 39 weeks. A search was conducted in the Medline via PubMed, UptoDate, Medscape and Google Scholar databases using the terms “Pregnancy and Chorea Gravidarum”. The search was limited to case reports and case series or review articles published between 2000 al 2019. Results: Seven case reports and one review of the topic were found. In 4 of the 7 cases, treatment was based on haloperidol, benzodiazepines and chlorpromazine. Penicillin was used in one of two cases with a history of Sydenham chorea. Maternal and fetal prognosis was good in 6 of 7 cases, there was 1 case of intrauterine growth restriction.

Conclusion:

Treatment of gestation chorea is primarily expectant and the goal is to reduce symptoms. Maternal and fetal prognosis is good.
