FIG 2. Infant born at 28 4/7 weeks.
A–D, Transient homogeneous periventricular densities are seen in the frontoparietal region on coronal and parasagittal sonograms at a PCA of 29 2/7 weeks (A). Coronal and parasagittal sonograms at a PCA of 34 4/7 weeks (B) show normalized echogenicity of the white matter with a homogeneous aspect. Axial T1-weighted (C) and T2-weighted (D) MR images on the same day show a frontal and parietal periventricular zone of mildly changed signal intensity.
