Craniosynostosis - The Radiology Assistant
When a craniosynostosis is suspected, the first line imaging will be ultrasound or x-rays, depending on local expertise and preferences. Because of lack of radiation, ultrasound is the preferred method. In case of high clinical suspicion low dose 3D CT is preferred.

Bilateral fusion of the lambdoid sutures results in turricephaly (tall cranium; also known as oxycephaly and acrocephaly), with bilateral occipitoparietal flattening that leads to a small posterior cranial fossa and unimpeded compensatory growth at bregma.

2019年3月1日 · We present the CT scan-derived turricephaly index (TI) as a quotient of the maximal occipito-frontal length of the skull to the distance from the centre of the sella to the highest point on the vertex as a validated tool for assessing turricephaly and evaluating surgical techniques aimed at reducing it.

2021年6月3日 · In a patient with Apert syndrome (a), narrowed and prolonged head appearance (turricephaly), flattened frontal and occipital bones, narrowed posterior fossa are observed on T2-weighted sagittal MRI. A case with bilateral lambdoid craniosynostosis ( b ) shows flattened occipital bone and accompanying thinning of the corpus callosum.

TI derived from the CT scout view provides a simple, objective and validated method for assessing turricephaly. We recommend it for monitoring and for the prospective evaluation of reconstructive techniques in children with complex/syndromic craniosynostosis.

2016年2月25日 · Sagittal images demonstrate the progression in severity of distorted turricephaly resulting from multi-sutural synostosis. a Sagittal T2-weighted MRI at 21 weeks’ gestational age. The subtle calvarial indentation at the vertex ( arrow ) is an early indication of craniosynostosis.

2016年5月10日 · Bilateral fusion of the lambdoid sutures results in turricephaly (tall cranium; also known as oxycephaly and acrocephaly), with bilateral occipitoparietal flattening that leads to a small posterior cranial fossa and unimpeded compensatory growth at bregma.
We have tried to distinguish turricephaly froni oxycephaly, both on clinical and on radiological grounds: in oxycephaly, the head is more pointed and fusion of the sagittal suture is more. Fig. 12.1. Turricephaly in a girl aged 3 months (cephalic index 95). Radiographs showed almost complete obliteration of both coronal sutures. D. J. David et al.,
Turricephaly - National Institutes of Health
Turricephaly is present when the head appears tall (subjective) and head length and width are reduced compared to normal age-related standards (objective). Head length is measured between the glabella (the most prominent point on the frontal bone above the root of the nose) and the most prominent part of the occiput in the midline, using ...
