Cerebral intraparenchymal hemorrhage in neonates: sonographic appearance

The real time sonographic findings of five neonates with cerebral intraparenchymal hemorrhage are reported. In each case, areas of markedly increased echogenicity corresponded to the site of hemorrhage. Excellent correlation was found between computed tomography (CT) and sonography. Although the sonographic appearance of intraparenchymal hemorrhage is characteristic, it is difficult to separate blood from other contiguous highly reflective structures in the head, including choroid plexus, bone, and the tentorium. It appears that real time sonography may offer an alternative to CT in the diagnosis of cerebroventricular hemorrhage in neonates.
