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.
