ReferenceStream Inches 300.00 As nouns the difference between hydrocephalus and hydrocephaly is that hydrocephalus is (uncountable|medicine) a usually congenital condition in which an abnormal accumulation of fluid in the cerebral ventricles causes enlargement of the skull and compression of the brain, destroying much of the neural tissue while hydrocephaly is hydrocephalus.
