Abstract:	Introduction Unilateral lambdoidal craniosynostosis is a rare disorder that occurs in approximately 3 % of all craniosynostosis phenotypes and only 0.03 % of one million live births. It is even more unusual for this type of synostosis to occur in siblings with only two other cases reported in the literature. Case report We report a set of full-term dizygotic twins born with lambdoidal synostosis and a family history of connective tissue and cardiovascular anomalies. One of the twins also had concomitant bicoronal craniosynostosis. Conclusion True familial lambdoidal synostosis is exceedingly rare. The present cases in dizygotic twins occurred in a family with a significant history of connective tissue disease suggesting a possible association.
