We sought to further characterize the cranial ultrasound and MR imaging characteristics and associated outcomes of this condition across the full range of gestational ages, including extreme and very preterm neonates. MATERIALS AND METHODS: This was a single tertiary pediatric center retrospective case series. Brain MR imaging and cranial ultra- sound of neonates with subpial hemorrhage with underlying cerebral infarct were identified from a population-based radiology registry (2006–2020).

The diagnostic utility of cranial ultrasound was com- pared with that of MR imaging. RESULTS: Sixteen patients were included (median gestational age, 36.5 weeks; range, 27–41 weeks; 31% premature).
