  • Hypothyroidism

    Newborn children with hypothyroidism may have normal birth weight and height (although the head may be larger than expected and the posterior fontanelle may be open).[en.wikipedia.org]

  • Medullary Thyroid Carcinoma

    Radiographic examination revealed typical widely separated cranial sutures and an open anterior/posterior fontanel with an obtuse gonial angle, acroosteolysis, and osteosclerosis[ncbi.nlm.nih.gov]

  • Congenital Hypothyroidism

    Examination revealed facial puffiness, open posterior fontanelles, dry skin, cold peripheries and prominent abdominal veins with visible peristalsis.[ncbi.nlm.nih.gov] She was severely pale with a wide open and flat anterior fontanel (3 3 cm), open posterior fontanel, depressed nasal bridge, macroglossia, dry skin, and an umbilical hernia[currentpediatrics.com] In fact, only about 5% of infants have detectable physical findings or symptoms at birth that may include: post-dates delivery macrosomia open posterior fontanelle umbilical[medicalhomeportal.org]

  • Autosomal Dominant Prognathism

    Posterior anterior view of skull reveals widened cranium and open anterior and posterior fontanelles.[amhsr.org] Lateral cephalogram revealed non-closure of sutures due delayed ossification of anterior fontanel, small wormian bones and enlargement of occiput was also obvious.[amhsr.org]

  • Cerebral Arteriovenous Malformation

    Physical signs of increased ICP: Lethargy, or a tense open anterior fontanel may be seen in infants with increased ICP.[ispn.guide] Global signs of increased ICP: Ataxia with nausea and vomiting can manifest as signs of increased ICP or with posterior fossa hemorrhage.[ispn.guide]
