Usually harmless
Most hemangiomas are 'quiet': they do not grow problematically and cause no pain. Seeing it on your MRI report can be worrying, but its presence alone is not a reason for alarm. These are watched or simply left untreated.
When does it cause symptoms?
In a small minority, a hemangioma becomes 'aggressive': it may cause persistent back pain, or grow enough to weaken the vertebra or press on the nerves. Only in these cases is treatment discussed; evaluation is done with MRI and clinical examination.
Treatment options
When needed, vertebroplasty (injecting bone cement to strengthen the vertebra) is a minimally invasive procedure that relieves pain and stabilizes the vertebra. In selected cases with nerve compression, surgery is used. The choice depends on symptoms and the state of the vertebra.
What to do if one was found
If your MRI mentions a vertebral hemangioma but you have no symptoms, usually nothing is needed beyond reassurance. If you have persistent pain related to the level, evaluation helps determine whether the hemangioma or another cause is responsible.
