[Sex-linked hydrocephalus: anatomical study (author's transl)]

Anatomical study of the brain of a boy with sex-linked hydrocephalus (Bickers and Adams, 1949) reveals complex malformations with agenesis of interhemispheric commissures, but without aqueduct stenosis. Discussion of these findings and of the relevant literature leads to the conclusion that, in this condition, hydrocephalus may be a primary consequence of brain malformation, and aqueduct stenosis, if present, a secondary phenomenon.
