Brachycephaly refers to a calvarial shape where the bi-parietal diameter to fronto-occipital diameter approaches the 95th percentile. It can result from a craniosynostosis involving the coronal and lambdoid sutures.
Brachycephaly can be associated with numerous syndromes which include:
- Apert syndrome
- Carpenter syndrome
- Cornelia de Lange syndrome
- cleidocranial dysostosis
- chromosomal anomalies
- Larsen syndrome
- Roberts syndrome
The head may appear rounder than usual on an axial scan and the cephalic index is increased.
