Fig 1.

A, Coronal T2-weighted image of a fetus with CDH at 24 weeks demonstrating expected maturation with the presence of the interhemispheric and Sylvian fissure (dashed arrow), but with an otherwise smooth appearance of the frontal lobes. There is expected visualization of the migrating neurons as evidenced by alternating dark and bright bands in the cerebral parenchyma (arrows) corresponding, from inside out, to the ventricular zone/germinal matrix, periventricular fiber rich zone, intermediate zone, subplate zone, and cortical plate. B, Coronal T2-weighted image of a 32-week fetus with CDH showing age-appropriate maturation with the presence of the superior and inferior frontal sulci (arrows) and the inferior temporal sulcus (dashed arrow). The 5 layer pattern of migration is no longer present.
