Extraventricular Obstructive Hydrocephalus

Extraventricular obstructive hydrocephalus is a form of hydrocephalus in which cerebrospinal fluid accumulates because its circulation or reabsorption is hindered outside the system of internal cavities of the brain, which increases the pressure inside the skull.

Common symptoms: It may manifest with headache, nausea, vision disturbances, or changes in the level of alertness; in infants, with an increase in head circumference.

When to see a doctor? Intense and persistent headache, vomiting, or neurological changes require care without delay.

Which specialist treats it? The neurosurgeon is the one who evaluates this condition and defines the approach; the general practitioner can guide the first visit and the timely referral.
