Bregmatic sutural bone: a case report

Abstract

Background: Sutural bones or wormian bones (an unusual anatomical variant associated with inadequate closure of suture) are extra intrasutural irregular isolated bones that occur additionally at the center of ossification of the skull; along sutures, around sutures or between the cranial sutures formed by bones of the skull vault. Case Presentation: This report displays a case of the presence of an unusual sutural bone at the bregma of the skull of a cadaver during maceration; hence revealing and supporting the possibility of variations in ossification centers and skull matrix which could aid neurosurgeons, orthopedics, and radiologists in their practices. Conclusion: The human bregmatic sutural bone presented in this report is a rare occurrence. Considering its location in the skull,it is the first kind reported in Nigeria and Africa as well as one of the few cases reported across the Globe.
