This was interesting: http://en.wikipedia.org/wiki/Hydrocephaly#Exceptional_case http://en.wikipedia.org/wiki/Hydrocephaly#Exceptional_case One interesting case involving a person with past hydrocephalus was a 44-year old French man, whose brain had been reduced to little more than a thin sheet of actual brain tissue, due to the buildup of fluid in his skull. The man, who had a shunt inserted into his head to drain away fluid (which was removed when he was 14), went to a hospital after he had been experiencing mild weakness in his left leg. In July 2007, Fox News quoted Dr. Lionel Feuillet of Hôpital de la Timone in Marseille as saying: "The images were most unusual... the brain was virtually absent."[9] When doctors learned of the man's medical history, they performed a computed tomography (CT) scan and magnetic resonance imaging (MRI) scan, and were astonished to see "massive enlargement" of the lateral ventricles in the skull. Intelligence tests showed the man had an IQ of 75, below the average score of 100 but not considered mentally retarded or disabled, either.
