Signs and Symptoms of Hydrocephalus
The signs and symptoms of hydrocephalus in infants and children vary depending on their age, the degree of hydrocephalus at presentation, the primary etiology, and the time over which the hydrocephalus develops. Ventriculomegaly can progress without obvious signs of increased intracranial pressure because of the plasticity of the infant brain and the ability of the cranium to expand.
In full-term infants, signs often include macrocephaly and progressively increasing occipital frontal head circumference, crossing percentile curves. Normal head circumference for a full-term infant is 33–36 cm at birth. A normal head circumference increases by approximately 2 cm/month during the first 3 months, by 1.5 cm/month during the 4th and 5th months, and by about 0.5 cm/month from months 6–12.
