Early vasculopathy following radiation in a child with medulloblastoma

A child with severe radiation vasculopathy 15 months following radiation therapy for medulloblastoma is reported. The patient underwent surgical resection of a posterior fossa medulloblastoma, followed by chemotherapy and radiation therapy. He was treated with 55 Gy to the craniospinal axis. Fifteen months later, the patient presented with a subacute neurologic deterioration from multiple ischemic events that resulted from severe radiation vascular injury. We compare and contrast this case to similar case reports in the literature.
