Posttraumatic isolated infarction in the territory of Heubner's and lenticulostriate arteries: case report.

A 12 year old male had a secondarily generalized epileptic seizure and a subsequent right hemiparesis with fasciobrachial predominance after a closed head injury. His seizures responded to antiepileptic drug therapy immediately. Computerized tomographic scanning and magnetic resonance imaging showed an acute infarct of the head of the left caudate nucleus, indicating the isolated occlusion of the left recurrent artery of Heubner and lateral lenticulostriate arteries. Pathologies leading to vasculitis and embolism were also looked for, but no finding of associated systemic disease could be disclosed. We present this case since posttraumatic infarction in the territory of the deep perforators such as recurrent artery of Heubner and lateral lenticulostriate arteries are exceptionally rare conditions especially in this age group.
