brachycephaly

Brachycephaly refers to a calvarial shape where the bi-parietal diameter to fronto-occipital diameter approaches the 95 percentile. It can result from a craniosynostosis involving the coronal and lambdoid sutures.

Pathology

Associations

Brachycephaly can be associated with numerous syndromes which include:

• Apert syndrome
• Carpenter syndrome
• Cornelia de Lange syndrome
• cleidocranial dysostosis
• chromosomal anomalies
  • trisomy 21 
• Larsen syndrome
• Roberts syndrome

Radiographic features

Antenatal ultrasound

The head may appear rounder than usual on an axial scan and the cephalic index is increased.
