If I have a arnold chiari malformation, what are the chances that my son will have these problems too?

Low: Chiari malformation can be isolated, occur secondary to spina bifida, or be part of many different patterns of birth defects (syndromes).

This implies a 2-3% risk for each of your children to have chiari. ...Read more

Symptoms may be mild (such as headache when sneezing) or more significant (imbalance/weakness). In lupus, ~ 70% of people can do very well while on therapy.
