Fig. 2.

Superior view of 3D reconstructions of brain (left) and skull (right) of a morphologically normal child (a), a child with SS (b), and a child with RUCS (c). In all views, the anterior aspect of the head is at the top while the posterior aspect is below. The brain and skull of the SS individual (b) is elongated along the anteroposterior axis and reduced medio-laterally. The sagittal suture is obliterated. The brain of the RUCS individual (c) is obviously deformed on the right anterior aspect and appears somewhat wider than normal. The RUCS skull shows dysmorphology of the right frontal bone and distortion of the sagittal and lambdoid suture patterns. The right coronal suture is closed while the left remains patent. Images are not to scale.
