What Is the Treatment for a Lesion on the Spine?

Treatment for a spinal lesion depends entirely on what the lesion is, because “spinal lesion” is a broad umbrella covering dozens of conditions, from infections and benign growths to metastatic cancer and inflammatory diseases like multiple sclerosis. A vertebral hemangioma that causes no symptoms may need nothing more than periodic imaging, while a spinal epidural abscess with neurological decline demands emergency surgery within hours. The first step is always accurate diagnosis, and from there, the path branches into surgery, radiation, drug therapy, minimally invasive procedures, or watchful monitoring.

Getting to a Diagnosis First

Before any treatment decision, clinicians need to know what they are dealing with. MRI is the primary tool for evaluating spinal lesions because it can distinguish between the spinal cord itself, the surrounding membranes, the vertebral bones, and the epidural space. When imaging alone does not provide a clear answer, a CT-guided percutaneous biopsy is often the next step. This technique uses a needle guided by live imaging to sample tissue directly from the lesion. It is used to confirm whether a known cancer has spread to the spine, to determine whether a solitary bone lesion is malignant, to rule out cancer in a vertebral compression fracture, and to investigate possible infection.¹ The biopsy result steers everything that follows.

Spinal Infections and Epidural Abscess

A spinal epidural abscess is a pocket of infected material that forms in the space surrounding the spinal cord. It is one of the more urgent spinal lesions because it can compress the cord and cause permanent paralysis if not treated quickly. The standard approach combines intravenous antibiotics with surgical drainage. Patients who already show neurological deficits, such as weakness, numbness, or loss of bladder control, generally need immediate surgical decompression.² Surgery removes the infected material and relieves pressure on the cord, while targeted antibiotics, typically given for several weeks through an IV, attack the underlying infection.³

Not every case goes straight to the operating room. In carefully selected patients who have no significant neurological problems and whose abscess is caught early, antibiotics alone can work, but this requires close monitoring with repeat imaging and neurological exams to ensure the infection is responding.⁴ The window for effective treatment narrows fast once nerve function starts to deteriorate, which is why physicians often err on the side of surgery when there is any doubt.

Inflammatory and Demyelinating Lesions

Spinal cord lesions caused by inflammation rather than a tumor or infection call for a fundamentally different approach. Two of the most common culprits are multiple sclerosis (MS) and transverse myelitis.

In transverse myelitis, the immune system attacks the spinal cord, causing sudden weakness, sensory changes, and sometimes bladder dysfunction. The immediate goal is to stop the inflammation. High-dose intravenous corticosteroids are the standard first treatment, and roughly half to two-thirds of adult patients regain the ability to walk with this approach.⁵ When steroids are not enough, plasma exchange, a procedure that filters harmful antibodies out of the blood, is sometimes used as a second-line treatment, particularly in pediatric cases or severe presentations.

For MS-related spinal cord lesions, acute flares are also treated with corticosteroids, but the long-term strategy revolves around disease-modifying therapies (DMTs) that aim to prevent new lesions from forming. Interestingly, research from a large MS registry found that higher-potency DMTs were significantly better at preventing new brain lesions and relapses compared to lower-potency options, but the difference in preventing new spinal cord lesions specifically was not statistically significant.⁶ That does not mean treatment is futile for spinal MS lesions, but it does suggest the cord may be harder to protect than the brain, and it underscores why ongoing monitoring matters.

Surgery for Spinal Tumors

When a lesion turns out to be a tumor growing within or around the spinal cord, surgery is often the centerpiece of treatment. Tumors that arise inside the spinal cord itself, called intramedullary tumors, are among the most delicate to operate on because the surgeon must work within the cord without damaging healthy nerve tissue. To help with this, surgical teams now routinely use intraoperative neurophysiological monitoring. This involves tracking electrical signals through the spinal cord during the operation. If the signals change in a way that suggests the cord is being stressed, the surgeon can adjust in real time, preventing permanent nerve damage in most cases.⁷ Multiple types of signals are tracked simultaneously: some monitor sensory pathways, others check motor pathways, and a specific type called D-wave recording provides a reliable indicator of the cord’s overall functional integrity.⁸

After tumor removal, especially for cancerous lesions, the spine may need to be rebuilt. The vertebrae that were opened or partially removed to access the tumor may no longer provide adequate support. Wound complications and failure of spinal reconstruction hardware are among the most common postoperative issues, which is why preoperative planning must account for how the spine will be stabilized after the tumor is out.⁹ Patients also need long-term surveillance for local tumor recurrence and distant spread.

Metastatic Cancer in the Spine

Cancer that has spread to the spine from elsewhere in the body is one of the most common reasons a spinal lesion is discovered. Breast, lung, prostate, kidney, melanoma, and thyroid cancers all have a tendency to metastasize to the vertebrae. Treatment for spinal metastases is rarely about curing the cancer; it is about controlling pain, maintaining the ability to walk, and preventing the spine from collapsing.

Not all spinal metastases require surgery right away. Some patients are initially managed conservatively with pain control, bracing, and radiation. However, among patients managed this way, a significant fraction eventually need an operation. One study found that about a quarter of conservatively managed patients were converted to surgery during follow-up, with the rate reaching roughly a third within the first year. The risk of needing surgery was higher when the tumor was located in the mid-thoracic spine or when the vertebral body had not yet collapsed past a certain threshold.¹⁰

Stereotactic Body Radiotherapy

For patients who are not good surgical candidates, or whose metastases are limited to a small number of sites, stereotactic body radiotherapy (SBRT) has become a powerful option. SBRT delivers highly focused, high-dose radiation to the tumor in just a few sessions, sparing the surrounding spinal cord. It achieves local tumor control in about nine out of ten patients at one year and carries a very low risk of neurological injury.¹¹ SBRT is increasingly used for what is known as oligometastatic disease, where only a few metastases are present and aggressive local treatment may meaningfully extend survival.

Proton Therapy for Specific Tumor Types

Certain rare tumors that grow in or near the spine, such as chordomas and chondrosarcomas, benefit from a different type of radiation. Proton beam therapy deposits most of its energy at a precise depth and then stops, unlike conventional X-ray radiation, which passes all the way through tissue. This physical property makes proton therapy particularly useful when the tumor sits right next to the spinal cord or other structures that cannot tolerate additional radiation.¹² It is typically used after surgery to eliminate any residual tumor cells.

Systemic Therapies and Bone-Targeting Agents

Because spinal metastases are a systemic problem, local treatments like surgery and radiation are usually combined with drugs that address the cancer throughout the body. Newer targeted molecular therapies and immunotherapy have shown improved responses compared to older chemotherapy regimens for many of the cancers that commonly spread to the spine.¹³ The specific drug depends on the type of cancer and its molecular characteristics.

Alongside cancer-directed therapy, bone-targeting agents help prevent the skeleton from breaking down. Both bisphosphonates (like zoledronic acid) and denosumab work by slowing the bone-destroying cells that tumors hijack to erode vertebrae. A meta-analysis comparing the two found that denosumab may be somewhat better at preventing pathological fractures, likely because it disrupts a key signaling pathway involved in bone resorption more completely than bisphosphonates do.¹⁴ These agents do not treat the cancer itself, but they reduce the risk of fractures, spinal cord compression, and the need for emergency radiation or surgery.

Vascular Lesions of the Spine

Abnormal tangles of blood vessels in or around the spinal cord, broadly called arteriovenous malformations or fistulas, are a distinct category. Left untreated, they can gradually steal blood flow from the cord, causing progressive weakness and sensory loss. Treatment options include embolization, where a catheter is threaded through the blood vessels and a material is injected to seal off the abnormal connection, and open surgery. Embolization is preferred for many of these lesions, provided the abnormal vessel and its draining vein can be completely blocked. However, surgery remains important for cases where embolization alone cannot achieve a complete seal, and a combined approach is common.¹⁵ The specific strategy depends on the hemodynamics and architecture of the individual lesion, which is why these cases are typically managed by a multidisciplinary team of neurosurgeons and interventional neuroradiologists.

Benign Vertebral Lesions

Not every spinal lesion is dangerous. Vertebral hemangiomas, for example, are benign vascular growths inside the vertebral bone that show up incidentally on imaging in a substantial number of adults. Most cause no symptoms and require no treatment. When they do cause pain or, rarely, grow aggressively enough to compress the spinal cord or nerve roots, a range of minimally invasive options is available.

Percutaneous vertebroplasty, where bone cement is injected into the vertebra to stabilize it and relieve pain, is used for hemangiomas that cause persistent back pain but no neurological problems. A systematic review found that about 14% of patients with aggressive vertebral hemangiomas were treated this way after failing at least six weeks of conservative management.¹⁶ For highly vascular lesions or those extending into the soft tissue around the spine, vertebroplasty may be combined with pre-procedural embolization to reduce blood flow, or with alcohol injection to shrink the growth.¹⁷ Surgery to decompress the cord is reserved for the small number of cases where the hemangioma causes real neurological compromise.

When Surgery Happens in Children

Spinal lesions in children present unique challenges. The growing skeleton is more vulnerable to the long-term consequences of surgery, particularly post-surgical spinal deformity. When a tumor needs to be removed from within a child’s spinal cord, osteoplastic laminotomy, which involves temporarily lifting and then replacing the bony arch over the cord, is preferred over a traditional laminectomy that permanently removes it. The cervical spine is especially prone to developing curvature problems after laminectomy.¹⁸ The surgical technique for removing the tumor itself is similar to what is used in adults, with total removal achievable in the large majority of cases depending on the tumor type. The difference lies in the painstaking care taken to reconstruct the spinal canal and the routine use of bracing afterward to protect the developing spine.¹⁹

Why Surgical Timing Matters So Much

For traumatic spinal cord injuries and certain acute compressive lesions, the clock starts ticking the moment damage occurs. Evidence from large multicenter trials and pooled analyses shows that decompressing the spinal cord within 24 hours of injury offers roughly three times the odds of a meaningful neurological improvement compared to delayed surgery.²⁰ The benefit is strongest for injuries to the cervical cord and for incomplete injuries, where some neurological function is preserved below the level of damage. In thoracic injuries and patients with multiple traumatic injuries requiring stabilization, the evidence is less consistent, partly because these cases are more complex and sometimes preclude immediate surgery.

Rehabilitation and Recovery After Spinal Cord Damage

Whether a spinal lesion was treated with surgery, radiation, or medication, recovery often depends on what happens afterward. The spinal cord has limited regenerative capacity, but the nervous system can rewire itself to some degree through a property called plasticity, and rehabilitation aims to exploit this as aggressively as possible.

Functional electrical stimulation (FES) cycling, where electrodes stimulate the leg muscles to pedal a stationary bike, has shown strong results in people with chronic spinal cord injury. In one study, FES participants saw meaningful gains in muscle mass, with quadriceps mass about a third higher and fat infiltration in the muscles nearly half that of the control group. Muscle strength was also roughly a third greater, and quality-of-life scores were significantly better.²¹

Beyond exercise-based rehab, electrical neuromodulation, where stimulators are placed on or near the spinal cord to enhance its remaining signaling capacity, is gaining traction. Early clinical reports have shown that combining intensive rehabilitation with epidural spinal cord stimulation can help some people regain the ability to stand, take steps over ground, or improve hand function, even years after injury.²² These results are still in the realm of case series rather than large trials, but they represent a genuine shift in what is considered possible for people with chronic spinal cord damage.

Managing Pain from Spinal Lesions

Pain is one of the most persistent problems after spinal cord damage, regardless of the original cause. Neuropathic pain, the burning or shooting kind caused by damaged nerves themselves, affects a large proportion of people with spinal cord injuries and can be extraordinarily difficult to treat. Based on the available evidence, amitriptyline (an older antidepressant that also dampens nerve pain), gabapentin, and pregabalin have the strongest track record and are considered first-line options.²³ Many patients require combinations of these medications, and even then, complete pain relief is uncommon. Other approaches like spinal cord stimulation, physical therapy, and psychological support are typically layered on top of medication, because no single treatment consistently controls neuropathic pain on its own.

Stem Cells and Experimental Approaches

For spinal cord injuries where current treatments cannot restore lost function, stem cell therapy remains one of the most actively researched frontiers. The idea is to transplant cells that can replace damaged neurons, provide structural support for regrowing nerve fibers, or release growth factors that encourage the cord to repair itself. Researchers are investigating several cell types and are increasingly combining stem cell transplants with supporting technologies like gene editing to fine-tune the cells, biomaterial scaffolds to guide nerve regrowth, and tissue engineering to create a hospitable environment within the injury site.²⁴ None of these approaches have become standard clinical treatments yet, and the gap between animal studies and reliable human outcomes remains substantial. But the volume of clinical trials underway suggests that at least some of these strategies will enter routine practice within the next decade or two.
