Intracranial Hemorrhages

A germinal matrix zone hemorrhage, the most typical hemorrhage of the newborn, occurs between the head of the caudate nucleus and the thalamus. This area contains proliferating germinal cells and thin-walled, fragile blood vessels that are prone to rupture and bleed. The hemorrhage may extend into the ventricle or the hemispheric white matter. Primary ventricular hemorrhage arises from the choroid plexus. Subarachnoid hemorrhage, at the base or over the hemispheres, often is associated with asphyxia or the mother's hematologic disease and sepsis. Subdural hematoma, usually traumatic, results from a tearing of bridging or cortical veins (Fig. 14.2).
