Aim: Little is known about the prevalence of discrete white matter abnormalities (WMA) beyond the first years in children born extremely preterm (EPT) and the relation to neurodevelopmental outcomes. Our aim was to investigate the prevalence of discrete WMA in children born EPT and the relationship to neonatal white matter injuries (WMI), white matter (WM) volume, WM diffusivity and neurodevelopment. Methods: The study was a part of a longitudinal follow‐up study of EPT neonates. All children were scanned at Karolinska University hospital 2004–2007 (neonates) and 2014–2015 (children at 8–11 years). WMA was qualitatively assessed by visual inspection. Developmental assessment was conducted at 12 years. Results: In total, 112 children (median age 10.3 years, 56 girls) underwent MRI of the brain (68 EPT, 45 controls). In the EPT group, a subset had MRI around term equivalent age (n = 61). In the EPT group, the prevalence of discrete WMA at 8–11 years was 52%. There was a positive association between WMI at TEA and 8–11 years. There was no association between WMI and WM volumes or diffusivity at 8–11 years. Discrete WMA was not related to neurodevelopmental outcomes. Conclusion: Discrete WMA was prevalent in children born EPT at 8–11 years but were not related to neurodevelopmental outcomes.
