Internal Hydrocephalus

Illustration of Internal Hydrocephalus intended for textbooks. Text in this illustration: Internal hydrocephalus is characterized by an obstruction of the Aqueduct of Sylvius, a conduit joining the third and fourth ventricles, and a subsequent disruption of the normal flow of cerebrosopinal fluid (CSF). In infants and toddlers, build up of internal cranial pressure within yet fused skull bones produces extensive enlargement of the vault (head). With advancement of the condition torpor will set in and later retraction of the upper eyelids and downward turning (sunset) eyes. Once routinely fatal, surgery has allowed for amelioration of deleterious symptoms associated with this condition. At present the most effective treatment involves insertion of a ventricular catheter into the cerebral ventricles to bypass the source of obstruction and disperse fluid into the abdominal cavity where it can be reabsorbed into the bloodstream.
