Original Article Spectrum and Prevalence of Vasculopathy in Pediatric Neurofibromatosis Type 1

To describe the spectrum and associated clinical features of peripheral and cerebral vasculopathy in pediatric patients with neurofibromatosis type 1, children seen at a single center from 2000 to 2010 with appropriate imaging studies were identified. Scans were assessed for vascular disease by 2 pediatric neuroradiologists. Of 181 children, 80 had pertinent imaging studies: 77 had brain imaging, 6 had peripheral imaging, and 3 had both. Vasculopathy was identified in 14/80 children (18%, minimum prevalence of 14/181; 8%). Of those with vascular abnormalities, 2/14 had peripheral vasculopathy (1 % minimum prevalence) and 12/14 had cere-brovascular abnormalities (7 % minimum prevalence). No associations were found between vasculopathy and common clinical features of neurofibromatosis type 1, including optic pathway glioma, plexiform neurofibroma, skeletal abnormalities, attention-deficit hyperactivity disorder (ADHD), or suspected learning disability. Both peripheral and cerebral vasculopathy are important complications of pediatric neurofibromatosis type 1 and should be considered in the management of this complex disease
