Abnormality of the skeletal system:Anomalies of the skull:1. Cranioschisis; opening in the cranial vault; if it was a large opening it may be associated with degeneration of the brain and is called Anencephaly. Small opening may be associated with herniation of the brain and is called meningoencephalocele, or there may be herniation of the meninges only forming meningocele.
Slide2Slide32. Craniosynostenosis; premature closure of the skull sutures leading to abnormal skull shapes. Involvement of the sagittal suture leads to scaphocephaly, involvement of the coronal suture leads to acrocephaly , involvement of both sagittal and coronal sutures on one sides leads to plagiocephaly.3. Microcephaly; under development of the skull that if severe it may be associated with underdevelopment of brain & mental retardation.
