Bilateral Coronal Synostosis


CR – Poorly developed anterior cranial fossa with recessed superior orbital rims and forehead. Note the markedly accentuated convolutional markings of the anterior inner table of the skull.

CT – 3D volume rendered image shows minimal vestiges of the coronal sutures at the vertex and nonvisualization inferiorly.


Craniosynostosis is the result of lack of formation or premature closure of sutures. Sutures permit skull growth perpendicular to themselves. Synostosis is usually sporadic but can have a genetic predisposition. Suture involvement in decreasing order of prevalence is sagittal, bilateral coronal, unilateral coronal, metopic and lambdoid. Sagittal synostosis is more common in males whereas coronal synostosis is more common in females.
