Ontogeny of recurrent hydrocephalus: Presentation in three fetuses in one consanguineous family

A consanguineous couple had 3 pregnancies in which prenatally diagnosed hyd rocephalus was observed (in 1 female and 2 male fetuses). This case appears to represent an autosomal recessive form of hydrocephalus, given the consa nguinity, affected sibs of both genders, and no evidence for intrauterine i nfection, chromosome abnormality, or neural tube defect.
