Radiographic features of craniometadiaphyseal dysplasia, wormian bone type.
Overview
abstract
We describe the radiographic findings in two siblings with a previously unrecognized craniotubular bone dysplasia. We call this condition craniometadiaphyseal dysplasia, wormian bone type. Because the parents of the siblings are consanguineous, this is probably a genetically determined condition with an autosomal recessive type of transmission. The findings in the siblings are compared with those of a woman with the same condition, previously reported as an example of craniometaphyseal dysplasia. The combination of findings in these patients seems diagnostic: characteristic skull changes including multiple wormian bones; wide long tubular bones without normal metaphyseal flaring; wide short tubular bones without normal diaphyseal constriction and sometimes actual diaphyseal expansion; and wide ribs and clavicles.
