What's the difference between hydrocephalus and hydrocephaly?
Hydrocephalus
Definition:
(n.) 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.
