1)To review the causes and imaging findings of craniosynostotsis 2)To demonstrate the post-operative appearances of the skull after craniectomy and to discuss some of its complications

Craniosynostosis is the premature fusion of the cranial sutures. It can present as an isolated finding or associated with a syndrome. Patients with diffuse craniosynostosis are at risk of developing increased intracranial pressure. Simple and compound forms of craniosynostosis causing scaphocephaly, trigonocephaly, plagiocephaly and brachycephaly will be presented in this essay using high quality cross sectional CT images with 3D and MIP reconstruction. We will also illustrate the role of CT scan in assessing patients who had undergone craniectomy for the treatment of craniosynostosis.

1) 3D CT scan is important in the preoperative and postoperative assessment of patients with craniosynostotsis. 2) Radiologist should be familiar with the imaging findings, the optimal CT technique, and the differential diagnosis of this condition.
