My son suffered from a brain tumor aged 2 (craniopharyngioma). He is now 21 and his current VP shunt was put in place in 2001. In the last 2 years, Every 3 months it appears to go through an episode which starts with twinges in the shunt pipe (resevoir) at the back of the head. This then increases over about 5 days and it is as if the shunt is blocking and then partially releasing but the pressure is remaining and growing. We eventually end up going to hospital and nothing shows up on scans etc. We are going through one of these periods at present and my bet is we will be in hospital tomorrow. It tends to the clear itself when the pressure gets so great it is unbearable. Anyone have had a similar experience??
