Indications for neurosonographic examination are:

  1. Hydrocephalus (enlargement of the head).
  2. Intracranial hematoma.
  3. Brain damage due to hypoxemia.
  4. Meningocele and other congenital anomalies.
  5. Convulsive syndrome.
  6. Too small head (microcephaly).
  7. Bulging of fontanelles (with increased intracranial pressure).
  8. Injury.
  9. Intrauterine infections.
  10. After meningitis, to exclude closure of the aqueduct of Sylvius or other complications.

Absolute indications for neurosonography:

Age

Newborns

1 month of life

  • gestational age less than 36 weeks;
  • birth weight less than 2800 g;
  • Apgar score at 5 minutes less than 7 points;
  • clinical signs of CNS damage;
  • multiple stigmas of dysembryogenesis;
  • respiratory distress syndrome,
  • infectious diseases in mother and child;
  • deterioration of condition, transfer to the intensive care unit.
  • gestational age less than 36 weeks;
  • birth weight less than 2800 g;
  • presence of clinical signs of damage to the nervous system;
  • multiple stigmas of dysembryogenesis;
  • history of chronic intrauterine hypoxia and/or birth asphyxia.

The standard of hyperechogenicity in normal ultrasound anatomy of the brain are the bones of the skull, vascular plexuses of the lateral ventricles, and anechoicity is the cerebrospinal fluid-containing structures (ventricles of the brain, cisterns).
