Figure 1.

Skull radiographs show brachycephalic skull with increase biparietal diameter, frontal bossing, wide spaced sutures, multiple sutural (wormian bones), and absent parietal bone ossification. The anterior fontanelle remains open, associated with posterior occipital synchondrosis. Closure of the sutures is markedly delayed, and the anterior fontanelle are markedly enlarged. Persistence of the cranial fontanelles, especially the bregmatic, with diastasis of the sutures and a membranous texture upon palpation of the papyraceous cranium are constant features in CCD.
