What does a suspicion on the left occipital avm mean?

Im 25 yrs old and had to have an mri scan due to symptoms which occurred, Ive been sent a report from the hospital which indicates what they found on the mri scan, and they haven't told me what it is or how serious it is or what the long term effects are, I'm wondering if someone could answer these questions for me, I have tried ringing the hospital but they are useless and won't give me any information, they said if I get any more symptoms to call 999 immediately which is not any help to me. Please help :)

The doctor seems to think you fall into a low risk group. Some conditions also are better off leaving alone and watching due to surgical risks of making it worse. I would suggest a private physician, a regular internist, to get your records and explain, since it seems the hospital won't take the time.
