Dandy Walker Variant
by Jose Pablo, Jul 14, 2000 12:00AM
My son was diagnose with DW Variant. He has a Hipoplasia of the vermis cerebeloso and a link between the fourth ventricle and with a Mega Cisterna Magna. He didn´t presents hydrocefalus or callosal agenesis. He reacts as a normal infant of 6 months.
He also has an asimetric in the morphology of the bones, where were a small hipoplasia of the right pariento occipital, with no cerebral malformations.
The orbits are normal and the movement of the eyes are also normal.
He was also has a CIV. (Small Cavity Intraventricular) in the Heart. Not afeccting the grown.
My questions are:
1. Is necessary to put the shunt now, or I have to wait until the hydrocephalus appears?
2. What chance does he have to never develop the hidrocephalus?

Dear Jose:
Sorry to hear about your son. No, I would not place a shunt in your son now. Only about 15-20% of infants with full Dandy-Walker will develop hydrocephalus. So, the odds are in your sons favor of never developing hydrocephalus. I would make sure that cognitive function is followed closely as there is an association between neuronal migration disorder and the Dandy Walker malformation (chance for learning problems). Since the vermis is involved, there is also a chance for body stability problems, but I am sure that your pediatrician has already talked to you about these things. I hope your son will do well.
Sincerely,
CCF Neuro MD
