Familial hydrocephalus presents a very considerable morphological and etiological heterogenecity. It can be a manifestation of several autosomal dominant or recessive syndromes. The non-syndromal forms include autosomal X-linked or recessive types and these tend to be recurrent. We report for the first time in the literature on two families with recurrent congenital hydrocephalus each for the fourth time. The first showed evidence of X-linked recessive form, while the second was an autosomal recessive form. The objective of these reports is to highlight the need for proper counseling of such families.
