Neonatal intracranial hemorrhage (ICH) represents a significant challenge in perinatal neuroimaging due to its variable etiology, presentation, and long-term impact on neurodevelopmental outcomes. This pictorial review aims to provide a comprehensive review of the magnetic resonance imaging (MRI) characteristics of hemorrhagic lesions in the neonatal brain. This includes detailing the appearance and evolution of blood products in neonates, the familiar sites and etiologies of ICH, and how these findings differ between preterm and term infants. The presentation will also address the unique imaging features of hemorrhagic lesions in the immature brain and discuss their neurodevelopmental outcomes. Key objectives include: 1. Explore the typical MRI appearances of blood products at different stages of a neonatal brain hemorrhage.. 2. Analyze the evolution of parenchymal and extra-axial hemorrhages, noting differences in imaging findings based on gestational age. 3. Understand the common causes of neonatal ICH, including perinatal trauma, hypoxic injury, and clotting disorders, and their multifactorial nature. 4. Discuss the neurodevelopmental implications of neonatal ICH, including the potential for impaired outcomes related to the location and size of hemorrhagic lesions. This abstract emphasizes the critical role of early and accurate imaging in diagnosing and managing neonatal hemorrhagic lesions, contributing to improved outcomes in affected infants. Read More
