If you have recently undergone an MRI or CT scan for back pain and seen the words “Vertebral Hemangioma” in your report, your first instinct might be to worry. The term “tumor” or “lesion” often triggers immediate anxiety.
However, in the vast majority of cases, a spinal hemangioma is a benign discovery that requires nothing more than observation. At the Bangalore Spine Specialist Clinic, we believe that an informed patient is a confident patient. This article aims to demystify this common spinal condition and explain when it needs treatment and when it can be safely ignored.
What is a Spinal Vertebral Hemangioma?
In simple terms, a vertebral hemangioma is a benign (non-cancerous) collection of blood vessels located within the marrow of a spinal vertebra. Think of it as a “birthmark” or a small cluster of tangled veins inside the bone.
They are incredibly common, found in an estimated 10% to 12% of the general population. Most people live their entire lives with one without ever knowing it exists. They are usually discovered “incidentally”—meaning the patient was getting an imaging test for an unrelated reason (like a pulled muscle or a kidney stone check) and the hemangioma simply showed up on the screen.
Why Do They Form?
The exact cause of vertebral hemangiomas remains unknown. They are not typically hereditary, and they aren’t caused by injury, diet, or lifestyle choices. They are simply malformations of the vascular tissues that occur as the body develops.
While they can occur at any age, they are most frequently detected in adults between the ages of 30 and 50, and they are slightly more common in women than in men.
Symptoms: What Should You Look For?
The most important thing to remember is that 95% of vertebral hemangiomas are asymptomatic. They do not cause pain, stiffness, or any neurological issues.
However, in rare cases (less than 5%), a hemangioma is classified as “Aggressive.” An aggressive hemangioma can cause symptoms through a few different mechanisms:
Bone Expansion: The cluster of blood vessels grows large enough to expand the bone, causing localized aching pain in the back.
Weakening of the Vertebra: Because the hemangioma replaces normal bone tissue, it can weaken the structural integrity of the vertebra, potentially leading to a compression fracture.
Spinal Cord Compression: If the hemangioma expands into the spinal canal or causes the bone to bulge, it can put pressure on the spinal cord or exiting nerves. This may lead to:
Numbness or tingling in the legs.
Weakness in the feet or difficulty walking.
In severe cases, changes in bladder or bowel control.
Diagnosis: The “Polka-Dot” Sign
Because hemangiomas rarely cause symptoms, they are diagnosed through high-quality imaging.
X-rays: May show a characteristic “honeycomb” or “jail-bar” appearance due to the way the blood vessels displace the vertical struts of the bone.
CT Scans: Offer a detailed look at the bone structure. On a CT cross-section, a hemangioma often looks like a series of small dots, famously known among radiologists as the “polka-dot sign.”
MRI: This is the gold standard for evaluation. It helps spine specialists distinguish between a standard, fat-rich hemangioma (which is harmless) and an aggressive, blood-rich hemangioma that might need intervention.
Treatment Options
If your hemangioma is asymptomatic (incidental), the standard treatment is observation. We generally recommend a follow-up scan in 6 to 12 months to ensure it isn’t growing, but otherwise, no lifestyle changes are necessary.
If, however, the hemangioma is causing pain or neurological symptoms, Dr. Shashidhar B.K. and the team at Bangalore Spine Specialist Clinic may consider the following interventions:
- Vertebroplasty or Kyphoplasty
This is a minimally invasive procedure used if the hemangioma has weakened the bone. A specialized medical-grade bone cement is injected into the vertebra. The cement hardens quickly, stabilizing the bone, preventing fracture, and often “shuts off” the blood supply to the hemangioma, which relieves pain. - Sclerotherapy
This involves injecting a chemical (sclerosant) directly into the hemangioma to cause the blood vessels to shrink and scar down. This is often done under CT guidance. - Radiation Therapy
In cases where the hemangioma is aggressive but surgery is too risky, low-dose radiation can be used to shrink the vascular tissue and stop its growth. - Surgical Decompression
If the hemangioma is significantly pressing on the spinal cord and causing weakness or paralysis, surgery may be required. The surgeon removes the part of the bone pressing on the nerves and may perform a spinal fusion to ensure the back remains stable.
Frequently Asked Questions
Can a hemangioma turn into cancer? No. A vertebral hemangioma is a benign vascular lesion. It does not spread to other parts of the body (metastasize) and does not “turn into” a malignant tumor.
Should I stop exercising? In the vast majority of cases, no. If the hemangioma is small and incidental, you can continue with yoga, gymming, and sports. If the lesion is very large, your surgeon might advise avoiding high-impact contact sports, but this is rare.
Is surgery always necessary? Absolutely not. Surgery is the last resort, reserved only for patients who have progressive neurological symptoms like leg weakness or loss of balance.
When to See a Specialist
If you have been diagnosed with a vertebral hemangioma, it is wise to have the imaging reviewed by a dedicated spine specialist. While most are harmless, a specialist can identify “red flag” features on an MRI that might suggest the lesion could become problematic in the future.
At Bangalore Spine Specialist Clinic, Dr. Shashidhar B.K. provides a comprehensive evaluation of spinal lesions, ensuring that patients receive a clear diagnosis and a personalized management plan.
Summary for Patients: Don’t let the word “tumor” scare you. A spinal hemangioma is usually just a quiet part of your anatomy. If you have chronic back pain or concerns about your scan, a consultation can provide the peace of mind you need.
