can't really help you here dm...i don't know much about spinal hemamgioma's...the "cosmetic" " birthmark" kind...i'm an expert. lil'monkey had one that almost killed her.
can be heavy bleeder..unless they have shrivled and don't have active tissue. inthe spine the dr's need to be aware...like mrsd said...they can be nicked and that is dangerous.
now if you had spondylolisthesis.....both mrsd and could help you lots.
