18 Possible Causes for Widened Metopic Suture

  • Donnai Barrow Syndrome
  • Cleidocranial Dysplasia

    Large head Thinness and underossification of calvarium in early infancy Widened fontanelles and sutures with delayed closure Persistent metopic suture Midline suture in frontal[learningradiology.com] Standard radiography and computed tomography frequently reveal large fontanelles, widened skull sutures, particularly visible at the metopic suture, protruding frontal and[symptoma.com] […] sagittal sutures and/or fontanelles premature fusion of the coronal suture ( brachycephaly ) frontal and/or parietal bossing basilar invagination (atlantoaxial impaction)[web.archive.org]

  • Nager Syndrome

    CT scan of mid-face with 3D reconstruction revealed widening sutures of skull notably the metopic suture, which was seen widening till the root of nasal bone with shallow[omicsonline.org]

  • Trigonocephaly

    Also known as trigonocephaly The metopic suture is located at the front of the head and separates the frontal bones.[ohsu.edu] It allows for transverse growth of the frontal bones and a widening of the anterior cranial fossa as the brain grows.[ohsu.edu]

  • Encephalocele

    Here, we present several patients with myelomeningocele, severe hydrocephalus, and interfrontal encephalocele accompanied by metopic suture widening and abnormally shaped[ncbi.nlm.nih.gov]

  • Craniosynostosis

    This creates a foreshortened anterior-posterior skull length and a widened appearance with a flattened back of skull. Trigonocephaly: A fusion of the metopic suture.[musckids.org] The premature closure of the metopic suture typically leads to a triangular shape of the forehead, and compensatory widening of of the posterior skull. ie trigonocephaly.[dr-bianca-knoll.com] The plain radiography of this 1-month-baby does not show the wide open metopic suture. However, it demonstrates the sclerotic fused suture.[ncbi.nlm.nih.gov]

  • Craniosytosis Type 4

    Metopic synostosis The metopic suture is located at the front of the head and separates the frontal bones.[ohsu.edu] The premature closure of the metopic suture typically leads to a triangular shape of the forehead, and compensatory widening of of the posterior skull. ie trigonocephaly.[dr-bianca-knoll.com] It allows for transverse growth of the frontal bones and a widening of the anterior cranial fossa as the brain grows.[ohsu.edu]

  • Blepharofacioskeletal Syndrome

    Large anterior fontanelle, widened metopic suture, thickened frontal bone, absent pneumatisation of the mastoid air cells and a hypoplastic mandibular condyle. ( g, h ) Subluxation[nature.com]

  • Pyknodysostosis

    Large head Thinness and underossification of calvarium in early infancy Widened fontanelles and sutures with delayed closure Persistent metopic suture Midline suture in frontal[learningradiology.com] […] dwarfism or defective or delayed dentition No mental retardation Imaging Findings Skull Wormian bones Intersutural bones, especially seen in the lambdoid and posterior sagittal sutures[learningradiology.com]

  • Isolated Synostotic Plagiocephaly

    When the sagittal suture is closed the skull can’t widen, so the remaining open sutures must create more bone to make room for the growing brain.[childrens.com] The orientation of the remaining open sutures – the coronal, lambdoid and metopic sutures – can only create bone perpendicular to their axis.[childrens.com]
