Multiple sutural bones at the lambda

Wormian bones of the cranial vault are formations associated with insufficient rate of suture closure, and regarded as epigenetic and hypostatic traits. These bones rest along sutures and/or fill fontanelles of the neonatal skull. These cases displays the possibility of discrete diversification of the ossification centers, as well as the relative stability of the structural skull matrix in response to discrete changes. We found three skulls with multiple suturai bones at lambda. Knowledge of this variation is very important for anthropologists, radiologists, orthopaedic and neurosurgeons.
