craniosynostosis radiology ultrasound

Ultrasound may be useful in subtle cases. Kadom N, Sze RW. In cases of isolated, nonsyndromic craniosynostosis, the sagittal suture is most commonly involved (39%–57%), followed by unilateral or bilateral coronal sutures (17%–29%), metopic suture (10%–22%), lambdoid suture (5%–17%), and, rarely, multiple sutures (<10%) (see Fig. (2007) ISBN:0781738954. Minimizing the ionizing radiation dose to children is fundamental to pediatric radiology. Usually, these sutures do not close before 18 to 24 months of life. Fetal craniosynostosis is uncommon, but careful prenatal sonography may establish the diagnosis, which will greatly facilitate clinical management. Evaluation of skull symmetry and careful intracranial examination and general fetal evaluation must be made in every fetus with a skull contour abnormality. Craniosynostosis requires evaluation by specialists, such as a pediatric neurosurgeon or plastic surgeon. The current study was performed to assess the diagnostic accuracy of ultrasound compared to CT scan as a gold standard in the diagnosis of craniosynostosis. Med Ultrason. AJR Am J Roentgenol. 2016 Sep;18(3):378-85 Authors: Helfer TM, Peixoto AB, Tonni G, Araujo Júnior E Abstract Craniosynostosis is defined as the process of premature fusion of one or more of the cranial sutures. Characteristic dysmorphic head shapes are associated with each type of craniosynostosis. The fetal cranium comprises bony plates that are joined together by areas of dense fibrous tissue termed cranial sutures, comprised of the sagittal, coronal, lambdoid, and metopic sutures ( Fig. Ultrasound is a less expensive, nonradiating and easy-to-handle tool ensuring the diagnosis of craniosynostosis. Starting with identification in 1993 of an MSX2 mutation in a family with craniosynostosis, there have been more than 50 genes associated with craniosynostosis.

Request PDF | Ultrasound and MR imaging findings in prenatal diagnosis of craniosynostosis syndromes | Background Craniosynostosis syndromes are uncommonly encountered in the prenatal period. In a study by Linz et al, CUS confirmed a clinical diagnosis of craniosynostosis or plagiocephaly in a group of 411 infants. 4. These reasons, together with the problem of legal issues, make the need of a definite diagnosis for a crucial problem, even in single-suture craniosynostosis (SSC). Craniosynostosis results in predictable skull deformation based on the sutures involved. Nowadays, different methods can be applied for prenatal diag-nosis of craniosynostosis, such as two-dimensional (2D) and three-dimensional (3D) ultrasound, magnetic resonance imaging (MRI), computed tomography (CT) scan and, finally, molecular diagnosis. 6. (Figs. The authors used the diagnosis of craniosynostosis to compare subjective evaluation of image quality with objective diagnostic utility. Genes Involved in Syndromic Craniosynostosis : FGFR1-3, … Wood BC, Oh AK, Keating RF, Boyajian MJ, Myseros JS, Magge SN, Rogers GF. Heterozygosity for mutation in the gene encoding FGFR3 produces Muenke syndrome as well as other disorders in which craniosynostosis can occur (e.g., thanatophoric dysplasia type II and Crouzon syndrome with acanthosis nigricans). 13). DOI: 10.1002/uog.91 Prenatal ultrasound diagnosis of fetal craniosynostosis Secondary craniosynostosis occurs in relation to a variety of causes: The sagittal suture is most commonly involved (≈50%), where the lateral growth of the skull is arrested while anteroposterior growth continues, producing a narrowly elongated skull known as scaphocephaly (meaning boat-shaped) or dolichocephaly (from the ancient Greek for long, δολιχός: dolichos). The skull shape then undergoes characteristic changes depending on which suture(s) close early. Exceptions occur, as seen in cases of Saethre-Chotzen syndrome, where a higher incidence of cases may be familial.

During this period, infants that were referred to our department by a general practitioner or a paediatrician for skull deformity and suspicion of craniosynostosis underwent both a cranial US and a plain radiography or 3D-CT according to the practitioner’s prescription. Fetuses with early-onset craniosynostosis may present with abnormal cranial contour in the second trimester and, in certain craniosynostosis syndromes, with characteristic malformations of the hands and feet. AJR Am J Roentgenol. 24 (2): 507-22. hallkenm@gmail.com. More than 150 syndromes involving craniosynostosis have been described. 2010;194 (3_supplement): WS5-9. Dähnert W. Radiology review manual. Secondary craniosynostosis can occur, owing to deformational compressive forces, maternal or neonatal metabolic derangements (such as hypophosphatasia syndrome [ Chapter 51 ]), or teratogenic influences.
