Ataxia hemiparética en un infarto lacunar lentículo-capsular con evolución favorable: Algunas consideraciones fisiopatológicas

Abstract

Hemiparetic ataxia (HA) is a lacunar syndrome that presents with motor deficit and pyramidalism associated to ipsilateral ataxia out of proportion to such deficit. Topography of lesions is wide and acute infarcts have been recognized at the internal capsule, pons, thalamus, corona radiata and cortex. Symptoms are associated to involvement of pyramidal and corticopontocerebellar tracts. We report a 44-year-old male presenting with right hemiparesis and severe ataxia. The magnetic resonance imaging showed a subacute infarction of the left lenticular nucleus and internal capsule. The patient was treated with physiotherapy, anti platelet agents and statins and was discharged with an evident recovery.
