Recurrent artery of Heubner infarction in infancy

Classically, acquired occlusion of the recurrent artery of Heubner (RAH) results in hemiparesis with faciobrachial predominance. Infarction in the territory of the RAH represents a specific stroke syndrome not yet described in infancy with a range of motor and functional manifestations. An infant is described with apparent congenital infarction of the recurrent artery of Heubner. The child had prominent involvement of the contralateral upper extremity with athetosis. Neuroimaging changes were evident in the vascular territory classically attributed to the RAH. The clinician should suspect congenital RAH infarction in those infants with congenital upper-extremity athetosis.
