Abstract

The interparietal bone, Os Incae, is formed in a persistent mendosal suture. This suture is a normal variant in the human skull, well-known in anatomy and radiology textbooks. We report 11 children with craniosynostosis in the presence of an interparietal bone, five from Children's Hospital at Montefiore and six children from Children's Hospital Boston. The true incidence of an interparietal bone in patients with craniosynostosis or craniofacial anomalies is not known; nor are there recognized sequelae of an interparietal bone (bathrocephaly). Hypotheses regarding mechanisms that may contribute to the formation of an interparietal bone are discussed.
