The Relationship Between an Abnormally Large Fontanelle and Rickets or Hydrocephalus

Question

Does an abnormally large fontanelle in newborns indicate a condition of rickets or hydrocephalus, and is a brain CT scan necessary?

Answer

An abnormally large fontanelle may be due to calcium deficiency and usually requires further observation. If the prenatal examination is normal, and the baby’s diet, sleep, and mental state are good, there is no need to worry excessively. Observe the fontanelle again after the baby is 100 days old. If there is no improvement, consider a CT scan.
