title: Emotional facial paresis with striatocapsular infarction.
abstract: Emotional facial paresis (EFP) refers to hemifacial paresis of emotionally evoked or spontaneous smiling or weeping with preserved volitional movements of the face. The anatomical location for this phenomenon has been controversial. We report a 15-year-old boy with EFP. Follow-up MRI demonstrated infarction limited to the head of the caudate, putamen and anterior limb of the internal capsule on the contralateral side. This case lends support for selective damage at a striatal or capsular site in the production of EFP.
