Sometimes a “congenital anomaly” in a medical context is detected when the baby is in the mother’s womb, just after birth, or sometimes many years later. These include “diastematomyelia”, “tethered cord syndrome”, “Arnold Chiari malformation”, “thick filum terminal”, “fatty filum”, “trigonocephaly”, “scaphocephaly”, “craniosynositosis”, “brachycephaly”, “spina bifida”, “meningocele”, “meningomyelocele”, “midline closure defect” and “late fontanel closure”.
These are sometimes very serious disorders of bone development, observable from the outside as a part of the brain or spinal cord is exposed; and sometimes occult disorders that can only be found with advanced technologic examinations such as MR or CT.
If your gynecologist or neonatal pediatrician is suspicious of such an anomaly during examinations or ultrasound investigation before or just after birth and send you to a neurosurgeon; or if your baby is born with such a frightening visible abnormality, do not waste any time. Start looking for an experienced pediatric neurosurgery professor.
