Thanks for the prayers. As it turned out today, the cyst would ordinarily need to come out, but the ventricles are not large enough for the surgical instruments to fit into safely.
Without great detail this means no surgery right now and who knows, I may not have any problems. If it does become more symptomatic, then we go on with the removal.
Doc, said there could be a risk of brain damage if we do it now, wife said, how would we know.
