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. INTRODUCTION Trauma is known to cause a number of vascular complications in and about the head. Some of them are well known, such as occlusion of the extracranial vertebral and carotid arteries. 5 ) Also, occlusion of the main intracranial arteries due to nonpenetrating head injuries has been frequently observed in patients with minor head injuries, often without loss of consciousness. 10. 15) Spasm, emboli from the cervical portion of the internal carotid artery, dissecting aneurysm and thrombus formation have all been suggested as causes. 11, 15,16 ) But we know very little about posttraumatic
