Wormian bones. A marker of CNS abnormality?

Area of Science:

• Pediatric Radiology
• Developmental Pediatrics
• Neuroscience

Background:

• Wormian bones (WBs), or sutural bones, are accessory ossicles found within the cranial sutures.
• Their clinical significance, particularly in pediatric populations, requires further elucidation.
• Previous research suggests a potential association between WBs and various developmental anomalies.

Purpose of the Study:

• To determine the incidence of Wormian bones (WBs) in a pediatric cohort.
• To investigate the association between the presence of WBs and central nervous system (CNS) disorders.
• To evaluate WBs as a potential marker for early identification of CNS abnormalities in children.

Main Methods:

• Retrospective analysis of radiographic data from 515 infants and children.
• Identification and quantification of Wormian bones (WBs) in the study population.
• Correlation of WB presence with diagnosed central nervous system (CNS) disorders, including gross CNS disorders and minimal brain dysfunction syndrome.

Main Results:

• Wormian bones (WBs) were identified in 91 (17%) of the 515 children studied.
• A significant association was observed between the presence of WBs and central nervous system (CNS) abnormalities.
• Of the children with WBs, 90% exhibited gross CNS disorders, and 6% had minimal brain dysfunction syndrome.

Conclusions:

• The presence of Wormian bones (WBs) is strongly associated with abnormal central nervous system (CNS) development in children.
• Wormian bones may serve as a valuable, non-invasive marker for the early detection of CNS disorders.
• Early identification through markers like WBs can facilitate timely intervention and treatment for affected infants and children.
