DE BETOLAZA, Sofía; BOTTA, Cecilia; MARCHISSIO, Elizabeth  y  PERENDONES, Mercedes. Vascular hemichorea: a rare presentation of lacunar infarction. Rev. Urug. Med. Int. [online]. 2016, vol.1, n.2, pp.29-34. ISSN 2393-6797.

Chorea is a hyperkinetic movement disorder. It can be caused by a great variety of conditions: genetic, infectious, degenerative, metabolic, autoimmune, structural or related to drugs. A rare manifestation of brain vascular lesions, either isquemic or hemorrhagic, it generally affects one side of the body as part of the classic hemichorea-hemibalism lacunar syndrome. We present the case of a 67 year old male with risk factors for cardiovascular disease, admitted with the diagnosis of vascular hemichorea as the manifestation of a stroke. Although such presentation is described in most of our bibliography, it is important because of its low prevalence and, consequently, the fact that most general physicians have never had contact with patients suffering from this entity.

Palabras clave : chorea; vascular hemichorea.
