Results Of five cases,scaphocephaly was seen in one case and oxycephaly and brachycephaly were revealed in two cases respectively.All cases demonstrated the deepened impressions for cerebral gyri.The antedisplacement of the sphenoid body and the smaller orbit were seen in four cases.One case with oxycephaly demonstrated the enlarged supratentorial cerebral ventricles on CT.One case with brachycephaly showed a depressed skull,narrowing of the optic foramen and obvious protrusion of both eyes on CT.Conclusion The radiological manifestations of cranial stenosis were characteristic.
