Moyamoya syndrome after radiation therapy for optic pathway glioma: case report.
We present a 4-year-old girl with neurofibromatosis-1 who developed moyamoya syndrome characterized by bilateral stenosis or occlusion of the distal internal carotid arteries and their branches, leading to the development of an abnormal vascular network. In light of a literature review, the postradiation vasculopathy of the moyamoya type and its relationship with neurofibromatosis-1 are discussed.
