Spinal hemangioma: one in ten people has one, and almost none of them hurt.
The MRI report says hemangioma. The word tumor lands hard. For nearly everyone, it is an innocent bystander, and the pain has another source.
A vascular tumor in the spinal column, usually called a spinal or vertebral hemangioma, is a benign growth made mostly of blood vessels inside a vertebra, most often in the mid or lower back. They are extremely common, present in roughly 10 percent of people, usually appear in adults between 30 and 50, and the vast majority cause no symptoms at all. The ATNS Index of Neuroplastic Symptoms frames the key question precisely: is this a hemangioma that is causing symptoms, or an incidental hemangioma in a person whose symptoms are neuroplastic? The first is likely only when the size and location of the growth match the nature and location of the symptoms. When there is reason to doubt that match, neuroplastic symptoms, real pain produced by a sensitized brain and nervous system rather than by the growth, should be assessed as part of a complete evaluation.
This page is about understanding the condition and the role the brain and nervous system can play in it. It is not a diagnosis. Your own clinicians know your case.
What a spinal hemangioma is, and why the diagnosis comes first
A hemangioma is a benign tangle of blood vessels. When it sits inside a vertebra, one of the bones of the spine, it is called a vertebral or spinal hemangioma. They are among the most common findings on spinal MRI, seen in about one adult in ten, most often in the thoracic (mid-back) and lumbar (low back) spine. They are not cancer.
A very small number, well under one percent, are what radiologists call aggressive. These grow beyond the bone, weaken it, or push into the spinal canal, and they can cause back pain that matches their location, pain radiating along a nerve, or, most seriously, weakness, numbness and bladder or bowel problems from pressure on the spinal cord. Because untreated compression can cause lasting neurological damage, the first job for anyone with a hemangioma and symptoms is to have a specialist determine which kind it is.
The neuroplastic contribution
The ATNS Index of Neuroplastic Symptoms describes the diagnostic fork clearly. Either the hemangioma is causing the symptoms, or the hemangioma is an asymptomatic bystander and the symptoms are neuroplastic. The growth is more likely to be responsible when its size and location correspond closely to the nature and location of the symptoms. Where there is reason to doubt that correspondence, assessment for neuroplastic symptoms should be part of a complete evaluation.
Neuroplastic symptoms are real symptoms produced by learned pathways in the brain and nervous system, a sensitized alarm, rather than by ongoing damage in the body. They are not imaginary and they are not a sign that you are exaggerating. The scenario the index has in mind is a familiar one. Someone has back pain, an MRI is done, a hemangioma is reported, and the word tumor becomes the explanation. And the diagnosis itself can make things worse: once you believe there is a tumor in your spine, the brain's threat system treats every twinge as evidence, muscles brace, movement is avoided, and the nervous system becomes more sensitive. That is the fear-avoidance cycle, and an incidental finding is one of the most effective ways to start it.
What the research shows
Large imaging studies establish how innocent most of these growths are. A retrospective longitudinal MRI study of 1,000 patients, proposing a new classification, reports that vertebral hemangiomas are found in about 11 percent of autopsies, 26 percent of CT scans and 27 percent of MRI scans, and that 89 to 99 percent of them are asymptomatic.
A review of the diagnosis and management of vertebral hemangiomas puts the symptomatic fraction at roughly 0.9 to 1.2 percent of all spinal hemangiomas, with aggressive lesions accounting for around one percent of cases, and sets out the imaging features that distinguish them: extension beyond the vertebra, soft tissue mass, involvement of the spinal canal.
None of this research tests a neuroplastic explanation for back pain in people with incidental hemangiomas, and the index's recommendation rests on the wider evidence on central sensitization and chronic back pain, where incidental scan findings are a well-recognised driver of persistent pain. But the numbers above are the foundation: if 99 percent of hemangiomas do not hurt, a hemangioma is a poor default explanation for pain.
Signs the brain may be part of the picture
- Your specialist has reviewed the imaging and said the hemangioma is typical, contained and not aggressive.
- The pain does not sit at the level of the hemangioma, or it spreads and moves.
- Pain got worse after you learned about the growth.
- Pain tracks with stress, sleep, mood and worry.
- You have become fearful of bending, lifting or exercising.
Put the scan in its place
Sit comfortably for three minutes. In the first minute, say the facts out loud or in your head: about one person in ten has a spinal hemangioma, almost none of them hurt, and a specialist has looked at mine. In the second minute, bring your attention to the place your back actually hurts and describe it in neutral words: tight, warm, a dull band, a pulse. Notice whether it is where the hemangioma is. In the third minute, gently round and arch your back a few times while breathing out slowly, noticing that movement is safe. You are helping your brain uncouple a harmless finding from a frightening sensation.
A solution that addresses it
For pain that does not match the hemangioma, there is an approach that addresses the brain's contribution. Pain and symptom reprocessing starts with education about neuroplastic symptoms, then builds skills: somatic tracking (observing back sensations with curiosity rather than alarm), reducing the sense of threat, a graded return to bending, lifting and movement, emotional awareness and expression, and acceptance and commitment skills. For someone carrying the word tumor around, understanding that hurt is not harm is often where recovery begins. Trained clinicians deliver it, and digital programs are making it widely available. It is for the neuroplastic pain, not for an aggressive hemangioma, which needs specialist treatment.

What to do next
First, get the hemangioma properly characterised. Ask a spine specialist or radiologist whether it has any aggressive features, whether its level and size match your symptoms, and whether any follow-up imaging is needed. Seek urgent care for new or progressive leg weakness, numbness, difficulty walking, or any change in bladder or bowel control; these are signs of spinal cord compression and need immediate assessment regardless of cause.
Second, if the specialist is confident the hemangioma is incidental, ask the question the index poses: could my pain fit a neuroplastic pattern?
Third, if it might, start learning and practising. Let the scan result become what it is, a common and harmless finding, and return to movement with a paced plan.
Questions people ask
Can a spinal hemangioma cause back pain?
Rarely. Fewer than one percent of vertebral hemangiomas ever cause symptoms, and those that do are usually large, extend beyond the bone, or press on nerves or the spinal cord at a level that matches the pain. The ATNS Index of Neuroplastic Symptoms says a hemangioma is likely responsible only when its size and location correspond closely to the symptoms.
Is a spinal hemangioma a neuroplastic condition?
No. A hemangioma is a real benign growth. The neuroplastic question concerns the back pain that is often blamed on an incidental hemangioma that is not actually causing it. In that situation the index recommends assessing for neuroplastic symptoms as part of a complete evaluation.
What symptoms need urgent attention?
New or worsening leg weakness, numbness, difficulty walking, or changes in bladder or bowel control can signal spinal cord compression and need immediate medical assessment. Severe pain that matches the exact level of a large hemangioma also warrants prompt review.

Persistent symptoms deserve a proper medical assessment to rule out disease or injury before a neuroplastic explanation is considered.
