Intracranial Hemorrhage in Term and Late-Preterm Neonates: An Institutional Perspective

Examples of various anatomic distributions of intracranial hemorrhages in term or late-preterm neonates. A, IVH and associated ventriculomegaly are present. Tentorial subdural hemorrhage is also present, as well as hemorrhage overlying the bilateral temporal poles. Right temporal lobe swelling (asterisk) is present and associated with subpial hemorrhage (arrow). B, Left occipital subpial hemorrhage (single arrow) is present, as well as left parieto-occipital lobe parenchymal hemorrhage (asterisk). Linear low signal intensities (double arrows) suggest either venous congestion or thromboses. C, Intra- and periventricular hemorrhages are present. Linear intensities (black arrow) and nodular intensities (white arrows on T2* imaging) suggest a perimedullary vein congestion and/or thromboses. D, Subpial hemorrhage is seen (white arrow) with subjacent temporal lobe deformity and edema (black arrow). On T2* imaging, parenchymal hemorrhage is also seen (asterisk), as well as punctate intraventricular blood products. E, Combined left frontal subpial and parenchymal hemorrhages are shown on CT and MR imaging. Small falcine subdural hemorrhage is also shown (arrow). F, Bilateral cerebral convexity, posterior fossa, and tentorial subdural hemorrhages (arrows) are present in a neonate with hemophilia.
