Answers are grounded in this paper and cite their sources.
Higher doses of cranial irradiation to the circle of Willis and the presence of neurofibromatosis type 1 are key risk factors for moyamoya syndrome in pediatric brain tumor patients.
Moyamoya syndrome is a potentially serious complication of cranial irradiation in children, particularly for those patients with tumors in close proximity to the circle of Willis, such as optic pathway glioma. Patients who received higher doses of radiation to the circle of Willis and with neurofibromatosis type 1 have increased risk of the development of moyamoya syndrome.
