The purpose of this presentation is to illustrate that the high-amplitude reflecting structures in the fetal and neonatal brain can be explained by the echogenicity of their leptomeningeal coverings or leptomeningeal origins. The leptomeninges, especially the pia mater, constitute the "grand unifying theory of bright reflectors" in the fetal and neonatal brain. Images from fetal and neonatal sonograms were selected to illustrate the objectives above.
