Occlusive stabilizing unilateral TCA in a 3-year-old boy who presented with three TIAs and a basal ganglia infarct on MRI. (A) Conventional angiography at 11 days after stroke shows an irregular distal ICA stenosis (horizontal arrow) and a proximal MCA occlusion with the development of some abnormal moyamoya lenticulostriate collaterals (vertical arrow). MRA at 3 months (B) and 3 years (C) after stroke shows a persisting but unchanged MCA occlusion with some abnormal moyamoya collaterals (arrows). There is no contralateral involvement in time.
