My 15 year old daughter, Jurie, has Partial Agenesis of the Corpus Callosum (P-ACC). We knew she had dilated lateral ventricles, but we were just told that she has hydrocephalus. The neurologist has said she doesn't need a shunt. I am not so sure because she has all the classic hydrocephalus symptoms and has had them for years. She has had severe headaches and vomiting since she was around three years old, but the doctors never knew the reason why. She has also always been a little too aggressive and is getting even more so to her brothers and sister. She also had her eye pressures taken for the first time recently, and they were fairly high: right eye-28 mm Hg and left eye-25 mm Hg.
