|Figure 1: Axial CT scan of the brain showing dilated, parallel ventricles, with disproportionately
large occipital and lateral horns of the lateral ventricles (colpocephaly). The non-functional
shunt catheter is also seen within the ventricles. In addition, the inter-hemispheric
fissure is almost in total continuity (white arrowheads). These are all characteristic
of a partial agenesis of the corpus callosum.
