Hi i was diagnosed with a cavernoma on my brain stem November 2010 (my 20th birthday!) My memory of it is quite hazy as i was on quite alot of medication and being young and hut with the news i tried to block everything out so i apologise if anything in this post is confusing. Anyway my consultant said he wasn't willing to operate because of the depth so another consultant suggested i was refered to Sheffield for gamma knife. I went down in August 2011 and was told about the treatment etc. I remember being told the rays thicken the tumour so it reduces the chance of anymore bleeds. I also got told i would have yearly follow ups at my referring hospital but wont need anymore scans because it would still show? However looking on other forums etc over the years i've learned some people have had 6m-yearly scans to keep an eye. In December at my recent appointment with my consultant i expressed my concern i have started experiencing slight dizziness while lying down and i've been tripping over things a lot more, the weakness in my left side has gradually got worse too. He didn't seem bothered but eventually he said he will speak to the consultant at Sheffield and they came back and said they want me put me for a MRI (still waiting for that appointment 6 weeks later.) I've had quite a stressful year with family illness so this has been playing on my mind since that appointment. Just a couple of questions to anyone that has had a bleed after this treatment... How mild/sever were your symptoms compared to first when diagnosed? And what are the treatment options if there is a bleed? I've read some people go for surgery (depending on severity), some are just monitored even closely but no intervention needed? I might be jumping the gun a bit but i don't have that much confidence in my consultant to be honest. Would be nice to hear peoples personal experiences.
