title: Primary hydrocephalus in adolescence.
abstract: Six of a series of 90 patients with hydrocephalus in the first two decades of life were adolescents. Four of these patients had acute symptoms that were superimposed on a baseline of a marginally functional cerebrospinal fluid circulatory system. All 6 patients were believed to have congenital etiologies for their hydrocephalus despite its clinical presentation in the second decade of life.
