Pediatrics : the hygienic and medical treatment of children . the resultof pressure by an increase in the intraventricular fluid. Fig. 282,page 84/^. represents the brain of a child who died of congenitalinternal hydrocephalus, and well exemplifies the pathology of thedisease. 576 Diseases of the Nervous System The convolutions are flattened and the walls of the ventricles aremuch thinned by the intraventricular pressure,, while the ventriclesthemselves are much dilated. In some parts the cortex is less thanI cm. (I inch) in thickness. The amount of the fluid in thesecases varies from a few cubic centimeters to three or four litres. Thefluid has a specific gravity of about 1004. The earlier the hydrocephalic condition begins, the larger thecranium will become. We therefore find the very large heads, asa rule, to be of the congenital variety. The head is at times of sucha size as to cause difficulty in the dehvery, or the fluid may collectvery rapidly after birth, and the head soon assumes the character-istic appearance of hydrocephalus. Fig. 282. Hydrocephalic brain. Warren Museum. Harvard University, Fig. 283 represents the hydrocephalic skull at three 3^ears in com-parison with a normal skull of the same age. The face in these cases of hydrocephalus remains about the samesize as it would be normally, but usually looks much smaller fromthe disproportionate size of the cranium, which rests upon it likea globe. Symptoms.—The symptoms of congenital internal hydrocephalusare essentially those caused by pressure. We naturally, therefore,find the fontanels bulging and fluctuating, and the bones thin andforced out of position. The temporal and parietal bones diverge as^Key extend upward, while in the normal skull they ascend almost Hydrocephalus 577
