  • Description: <b><i>Introduction:</i></b> Brain injury patterns of preterm infants with perinatal asphyxia (PA) are underreported. We aimed to explore brain magnetic resonance imaging (MRI) findings and associated neurodevelopmental outcomes in these newborns. <b><i>Methods:</i></b> Retrospective multicenter study included infants with gestational age (GA) 24.0–36.0 weeks and PA, defined as ≥2 of the following: (1) umbilical cord pH ≤7.0, (2) 5-min Apgar score ≤5, and (3) fetal distress or systemic effects of PA. Findings were compared between GA <28.0 (group 1), 28.0–31.9 (group 2), and 32.0–36.0 weeks (group 3). Early MRI (<36 weeks postmenstrual age or <10 postnatal days) was categorized according to predominant injury pattern, and MRI around term-equivalent age (TEA, 36.0–44.0 weeks and ≥10 postnatal days) using the Kidokoro score. Adverse outcomes included death, cerebral palsy, epilepsy, severe hearing/visual impairment, or neurodevelopment <-1 SD at 18–24 months corrected age. <b><i>Results:</i></b> One hundred nineteen infants with early MRI (<i>n</i> = 94) and/or MRI around TEA (<i>n</i> = 66) were included. Early MRI showed predominantly hemorrhagic injury in groups 1 (56%) and 2 (45%), and white matter (WM)/watershed injury in group 3 (43%). Around TEA, WM scores were highest in groups 2 and 3. Deep gray matter (DGM) (aOR 15.0, 95% CI: 3.8–58.9) and hemorrhagic injury on early MRI (aOR 2.5, 95% CI: 1.3–4.6) and Kidokoro WM (aOR 1.3, 95% CI: 1.0–1.6) and DGM sub-scores (aOR 4.8, 95% CI: 1.1–21.7) around TEA were associated with adverse neurodevelopmental outcomes. <b><i>Conclusion:</i></b> The brain injury patterns following PA in preterm infants differ across GA. Particularly DGM abnormalities are associated with adverse neurodevelopmental outcomes.
