An accumulation of liquid within the cavity of the cranium, especially within the ventricles of the brain; dropsy of the brain. It is due usually to tubercular meningitis. When it occurs in infancy, it often enlarges the head enormously.
too much fluid in the brain. The brain is kept buoyant in the skull by cerebrospinal fluid, which is continually produced and reabsorbed. Either blocking the flow out of fluid, or reabsorption, will result in hydrocephalus. Only in infants does this enlarge the head, since the bones of the skull are not yet fused. Causes include congenital defects, meningitis, tumours, injury. Treatments include shunting, which drains the excess fluid out of the brain, generally into the abdominal cavity. It sometimes corrects itself.

(Brain) Increased accumulation of cerebrospinal fluid in the ventricles of the brain. Highest incidence in toy and brachycephalic breeds. Special Diagnostics: radiograph of skull; also MRI or CT scan.
Hydrocephalus is due to an imbalance in the production and absorption of cerebrospinal fluid (CSF). This causes the ventricles in the brain to swell, causing pressure on the surrounding tissue. The causes vary, but it is rarely genetic. The effects of hydrocephalus vary significantly, but the outlook for those where it is detected in the womb is generally very poor.

Hydrocephalus refers to an abnormal accumulation of fluid (cerebrospinal fluid) within cavities, called ventricles, inside the brain. Hydrocephalus can be congenital, caused by complex genetic and environmental factors, or acquired from spina bifida, intraventricular hemorrhage, head trauma, meningitis, tumors and cysts.
