Presentation transcript:

A, B. T2-weighted images obtained coronal and sagittal to the fetal head show fluid occupying the majority of the cranial vault (arrows) and absence of most cerebral tissue. The brainstem and cerebellum are hypoplastic. The falx cerebri is visible on the coronal image. There is partial formation of the central gray matter structures of the cerebrum. There are small areas of cerebrum in the inferior aspect of the right temporal lobe and in the posterior parietal-occipital region. The fetus is in a cephalic presentation, with the face directed anteriorly. Source: Congenital Abnormalities of the Brain, Diagnostic Imaging of Infants and Children Citation: Wells RG.
